jquery how to select all the class elements start with "text-"?

Question

I have got some classes

.text-1
.text-2
.text-3

I want to select them all, how to do that? Thanks for the help

Answer 1

Try this. For more details refer jquery selectors

$('*[class^="text"]')

Answer 2

Here's an attempt at a solution that's both accurate and not too slow:

var elts = $('*[class*="text-"]')
  .filter(function () {
    return this.className.match(/(?:^|\s)text-/);
  });

Which works by using the (hopefully) fast Sizzle code to find elements that have "text-" anywhere in their class attribute, and then calls a function on each of those to filter them down to the ones that actually have "text-" at the beginning of a class name.

Answer 3

You don't necessarily need to specify asterisk *, you can do this too:

$('[class^="text-"]')

Notice the addition of - after text something you are looking for.

Check out the jQuery starts with selector for more information.

Answer 4

You can do this with just two selectors in one function call:

$('[class^="text-"], [class*=" text-"]')

This will check if the class attribute starts with text- or if there is any part of the class string that has a space followed by text-. This solves any issues you might have with the

$('[class^="text-"], [class*=" text-"]')
    .css('background-color', '#00FF00'); // add background color for demo

/* just for demo */
div:after {
  content: "class: " attr(class);
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<div class="text-1 test"></div>
<div class="text some-text-1"></div>
<div class="nope text-long-class-name"></div>
<div class="some-text-1"></div>
<div class="even get text-n-here"></div>

You could pull this out into a function that selects all elements with a class that matches a given prefix, as well:

function selectElementsWithClassPrefix(prefix) {
    return $('[class^="' + prefix + '"], [class*=" ' + prefix + '"]');
}

Answer 5

Here's a function that deals with the issue of multiple classes, in cases like <div class="foo bar barfood">:

function classStartsWith(str) {
  return $('div').map( function(i,e) {
    var classes = e.className.split(' ');
    for (var i=0, j=classes.length; i < j; i++) {
      if (classes[i].substr(0, str.length) == str) return e;
    }
  }).get();
}

The function returns an array of matching DOM elements. You can use it thus:

$( classStartsWith('text-') ).doSomething();

Here's an example: http://www.jsfiddle.net/Ms6ey/3/

Of course this assumes the selector 'div'. The question seems to be asking about any element at all. It's easy enough to make the function take a selector as another argument, and use that in place of the hardcoded one in the example.

$('#qvDetails,#qvAdd,.qvFramedActive,#qvMoreSizes').live('mouseover',function(){

        $(this).addClass('qvHover');                                                                            

    });

example from one of my projects.you can mention both divs and classes together like above

you can provide as coma separated class or divs in the same...
