What is a Vanilla JS or jQuery solution that will select all of the contents of a textbox when the textbox receives focus? The funny part is that this does not happen on MSIE!

The problem here is the first mouseup event that forces to unselect the input content, so just ignore the first occurence.

The timeOut approach causes a strange behavior, and blocking every mouseup event you can not remove the selection clicking again on the input element. I know inline code is bad style, but I didn't want to put this into a.

Works without jQuery! If you click one of the buttons, and left the mouse over the button the number would keep changing as if you were holding the mouse button because the mouseup was being thrown away.

How to show and hide elements with vanilla JavaScript

I know there are already a lot of answers here - but this one is missing so far; a solution which also works with ajax generated content:. I was able to slightly improve Zach's answer by incorporating a few function calls. The problem with that answer is that it disables onMouseUp completely, thereby preventing you from clicking around in the textbox once it has focus.

This is a slight improvement over Zach's answer. It works perfectly in IE, doesn't work at all in Chrome, and works with alternating success in FireFox literally every other time. If someone has an idea of how to make it work reliably in FF or Chrome, please share. Like Travis and Mari, I wanted to autoselect when the user clicked in, which means preventing the default behaviour of a mouseup event, but not prevent the user from clicking around.

The solution I came up with, which works in IE11, Chrome 45, Opera 32 and Firefox 29 these are the browsers I currently have installedis based on the sequence of events involved in a mouse click. When you click on a text input that already has focus, the focus event is skipped. As Travis and Mari both astutely noticed, the default handling of mouseup needs to be prevented only if the focus event occurs. However, as there is no " focus didn't happen" event, we need to infer this, which we can do within the mousedown handler.

Mari's solution requires that jQuery be imported, which I want to avoid.

Travis's solution does this by inspecting document. I don't know why exactly his solution doesn't work across browsers, but there is another way to track whether the text input has focus: simply follow its focus and blur events. What is a JavaScript or jQuery solution that will select all of the contents of a textbox when the textbox receives focus?

Edit: Per DavidG's request, I can't provide details because I'm not sure why this works, but I believe it has something to do with the focus event propagating up or down or whatever it does and the input element getting the notification it's received focus.

Setting the timeout gives the element a moment to realize it's done so. If you chain the events together I believe it eliminates the need to use.

Ditching jQuery for Vanilla JS

Would make strUser be 2. If what you actually want is test2then do this:. Source Link.

The following script is getting the value of the selected option and putting it in text box 1. The following script is getting a value from a text box 2 and alerting with its value.

This eliminates the need for locating a form in the dom tree and then locating this element inside the form. We know all form elements need names, even before they get ids. The previous answers still leave room for improvement because of the possibilities, the intuitiveness of the code, and the use of id versus name.

One can get a read-out of three data of a selected option -- its index number, its value and its text. This simple, cross-browser code does all three:. For functional form purposes, name is still valid, also in HTML5, and should still be used. Lastly, mind the use of square versus round brackets in certain places. Note: The values don't change as the dropdown is changed, if you require that functionality then an onClick change is to be implemented. I have a bit different view of how to achieve this.

I'm usually doing this with the following approach it is an easier way and works with every browser as far as I know :. Inin Firefoxthe following also works. To go along with the previous answers, this is how I do it as a one-liner. This is for getting the actual text of the selected option. There are good examples for getting the index number already. And for the text, I just wanted to show this way.

I doubt this processes any faster than the two line version. I simply like to consolidate my code as much as possible. Unfortunately this still fetches the element twice, which is not ideal.This article was peer reviewed by Mev-Rael and Panayiotis Velisarakos.

This is useful in situations when you want your page elements to change in response to user actions. There are two JavaScript properties that let you work with classes: className and classList. The former is widely compatiblewhile the latter is more modern and convenient. Note: This tutorial assumes some familiarity with JavaScript concepts like functions and variables. Some string manipulation will let us add and remove classes. Notice that you can identify the HTML elements you want to change through a selector or you can directly pass in the elements themselves.

Our addClass function first takes two parameters: the HTML elements we want to modify and the class we want to add. Our goal is to loop through each HTML element, make sure the class is not already there, and then add the class. First, if the list of elements is empty, our function has nothing left to do, so we can get out early.

However, if DOM elements are fed into the function directly, we can loop through them. Most of this removeClass function works the same way as our addClass function; by gathering the desired HTML elements and looping through them. The only difference is the part where the class gets removed. First, we create a regular expression to look for all instances of our desired class. The 'g' means global match, which means find all instances of the pattern.

Using our pattern, we replace the class name with a space. In a previous articleCraig Buckler provided a list of things classList can do:. These functions will get all desired elements, loop through them, and add or remove a class to each one. When you can control CSS classes through JavaScript, you unlock a lot of functionality including content display updates, animations, error messages, dialogs, menus, and more.

I want to use jQuery to check each option's value against a Javascript var. If one matches, I want to set the selected attribute of that option.

How would I do that? In case your options have value attributes which differ from their text content and you want to select via text content:.

But if you do have the above set up and want to select by value using jQuery, you can do as before:. For the browsers that support document. None of the examples using jquery in here are actually correct as they will leave the select displaying the first entry even though value has been changed.

You can change the value of the select element, which changes the selected option to the one with that value, using JavaScript:.

I used almost all of the answers posted here but not comfortable with that so i dig one step furter and found easy solution that fits my need and feel worth sharing with you guys. Instead of iteration all over the options or using JQuery you can do using core JS in simple steps:. This will keeps url parameters shown as selected to make it more user friendly and the visitor knows what page or profile he is currently viewing. I used this after updating a register and changed the state of request via ajax, then I do a query with the new state in the same script and put it in the select tag element new state to update the view.

I didn't realize there was a selectedIndex. I used post-increment instead of pre-increment, and then I added another test which is slightly faster than your 3rd test.

Today, I want to share the process for going framework-free. One of the benefits of a framework like jQuery is that it smooths out all of the weird browser inconsistencies you might run into.

But, all that abstraction and extra code adds a lot of weight and performance latency to a site. Rather than trying to provide the same level of functionality for older browsers, I took a progressive enhancement approach to development. Older and less capable browsers get a basic experience. Newer browsers that support modern APIs get an enhanced one. They still have access to all of the content.

The BBC also tests for local storage support, but since none of my scripts use that at this time, I left it out. This does the mustard test, and if the browser passes, adds a. If any of my scripts also rely on CSS, I make them conditional on the presence of that class.

In my JavaScript file yes, just oneI use the same mustard test as a wrapper for my scripts:.

How to set multiple select box values using jquery

For getting objects by ID, I use querySelector. For IDs, there should only be one match per page. For classes, it would return the first element with that class. To get all objects with a particular class, I use querySelectorAll. For example, to get all elements with the.

It returns an array of elements a node list that I can loop through and work with. If you get all elements with a particular class, you most likely want to do something with them.

Doing so is easy with a for loop:. Taking action when someone clicks, uses their keyboard, and more is pretty easy thanks to the addEventListener method.

Unfortunately, it still lacks the browser support it needs for every day use. It extends support back to IE 8, and when classList support is good enough, I can just remove the polyfill from my projects without updating any of my code.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.
