How to set an option in select by text using jQuery? The following works $(\"#selectID option:contains(\'optionText\')\").attr(\"selected\", true);

How to set an option in select by text using jQuery? The following works

$("#selectID option:contains('optionText')").attr("selected", true);

Is there a simpler/shorter way?

Example

<select id="fruit">
    <option value="">--select--</option>
    <option value="1">apple</option>
    <option value="2">pineapple</option>
    <option value="3">orange</option>
<select>
<br>
<button>apple</button>
<button>orange</button>
<button>pineapple</button>

$(function() {
    $("button").click(function() {
        $("#fruit option:contains('" + $(this).text() + "')").attr("selected", true);
    })
})

Demo

EDIT

The version posted above using Contains has a bug. Since the Contains would match partial strings also (e.g. apple would match pineapple), it can开发者_JAVA技巧 select incorrect options.

// Doesn't work in FF4, IE9 using jQuery 1.4.4
$('#fruit').val('apple'); // Doesn't work in FF4, IE9 using jQuery 1.4.4

// Doesn't work either in FF4, IE9 using jQuery 1.4.4
$('#fruit option[text="apple"]').attr("selected", true);

// This works
$("#fruit").children("option[text='apple']").attr("selected", true);

// The above doesn't work in jQuery 1.7.1

// Using even more verbose version [Demo][2]

var buttonText = $(this).text();

$("#fruit option:contains('" + buttonText + "')")
    .filter(function(i){
        return $(this).text() === buttonText;
    })
    .attr("selected", true)


You should be able to do:

$('#fruit').val('apple');

Actually, in the NEWER versions of JQuery, this doesn't work, you're right. Only thing I can think of is this:

$('#fruit option[text="apple"]').attr("selected","selected");

Is that even better than yours? ;)

// Doesn't work in FF4, IE9 using jQuery 1.4.4
$('#fruit').val('apple'); // Doesn't work in FF4, IE9 using jQuery 1.4.4

$("#fruit option:contains('" + buttonText + "')")

        return $(this).text() === buttonText;
    })
    .attr("selected", true)


It can be achieved like so:

<select id="fruit">
<option value="">--select--</option>
<option value="1">apple</option>
<option value="2">orange</option>
<select>
<br>
<button data-id="1">apple</button>
<button data-id="2">orange</button>

JS

$(function() {
    $("button").click(function() {
         $("#fruit").val($(this).data('id'));
    });
});

This is just one way it can be done. You can also set your option values to 'apple' and 'orange' then use the following js instead.

$(function() {
    $("button").click(function() {
         $("#fruit").val($(this).text());
    });
});
