使用jQuery通过文本内容选择选项
问题描述:
我想将一个下拉框设置为使用jquery通过查询字符串传递的任何内容.
I want to set a dropdown box to whatever has been passed through a querystring using jquery.
如何将所选属性添加到选项中,以使"TEXT"值等于查询字符串中的某个参数?
How do I add the selected attribute to an option such that the "TEXT" value is equal to a certain param from the query string?
$(document).ready(function() {
var cat = $.jqURL.get('category');
if (cat != null) {
cat = $.URLDecode(cat);
var $dd = $('#cbCategory');
var $options = $('option', $dd);
$options.each(function() {
if ($(this).text() == cat)
$(this).select(); // This is where my problem is
});
};
});
答
替换此:
var cat = $.jqURL.get('category');
var $dd = $('#cbCategory');
var $options = $('option', $dd);
$options.each(function() {
if ($(this).text() == cat)
$(this).select(); // This is where my problem is
});
与此:
$('#cbCategory').val(cat);
在选择列表上调用 val()
会自动选择带有该选项的选项值(如果有).
Calling val()
on a select list will automatically select the option with that value, if any.
