jQuery 更改输入文本值

Question

I can't find the right selector for:

<input maxlength="6" size="6" id="colorpickerField1" name="sitebg" value="#EEEEEE" type="text">

I want to change the value to = 000000. I need the selector to find the "name" not the id of the text input.

Shouldn't this work?:

$("text.sitebg").val("000000");

The presented solution does not work, what's the problem with this?

$.getJSON("http://www.mysitehere.org/wp-content/themes/ctr-theme/update_genform.php",function(data) {
    $("#form1").append(data.sitebg);
    $('input.sitebg').val('000000');
});

The JSON data is working correctly; the idea is to later pass the JSON values into the form input text values. But is not working :(

Answer 1

no, you need to do something like:

$('input.sitebg').val('000000');

but you should really be using unique IDs if you can.

You can also get more specific, such as:

$('input[type=text].sitebg').val('000000');

EDIT:

do this to find your input based on the name attribute:

$('input[name=sitebg]').val('000000');

Answer 2

jQuery way to change value on text input field is:

$('#colorpickerField1').attr('value', '#000000')

this will change attribute value for the DOM element with ID #colorpickerField1 from #EEEEEE to #000000

Answer 3

最佳实践是直接使用标识：

$('#id').val('xxx');

Answer 4

设置元素的新值时，需要调用触发器更改。

$('element').val(newValue).trigger('change');

Answer 5

Just adding to Jason's answer, the . selector is only for classes. If you want to select something other than the element, id, or class, you need to wrap it in square brackets.

eg

$('element[attr=val]')

Answer 6

jQuery change input text value using parent class

$('.form-submit input.submit').val('Johnny Bravo');

• .form-submit is the parent class
• Johnny Bravo is the text that you want to change
