Filter elements out of a jquery object based on text content

问题

I am trying to use contains with 'this' keyword, but it is giving an error.

JS

$(function(){
    var check=$('ul').find('li').filter(function(){
        return $(this:contains('two')).css('color','red')
    })
})

HTML

<ul>
    <li id="one">one</li>
    <li id="two">two</li>
    <li id="one">one</li>
    <li id="two">two</li>
    <li id="one">one</li>
    <li id="two">two</li>
    <li id="one">one</li>
    <li id="two">two</li>
    <li id="one">one</li>
    <li id="two">two</li>
</ul>

回答1:

Is this what you are looking for?

Fiddle

$(function () {
    $('ul').find('li').filter(function () {
        return this.innerHTML == 'two';
    }).css('color','red')
})

Or to match it anywhere in the element (rather than only "two" being within it):

Fiddle

$(function () {
    $('ul').find('li').filter(function () {
        return /two/.test(this.innerHTML);
    }).css('color','red')
})

---

Also, if it matters... chaining methods (.find().filter()) seems to be faster than using contains:

And your id's should be unique - but I'm assuming that it is just copy/pasting for sample code and that you don't actually have duplicate id's in your actual code.

Without filter as simple as

$("ul li:contains('two')").css('color', 'red');

WORKING DEMO

回答3:

$(this).text() == 'two';

Get the current li's text & check if it has the value "two".
