我有一个 jQuery 脚本，可以将我的菜单重新组织成一个选择表单元素，它工作正常。
我想在 .resize() 事件上触发它，但我无法让它工作。我该怎么做？
$(function () {
$(window).resize(function () {
/* Get the window's width, and check whether it is narrower than 580 pixels */
var windowWidth = $(window).width();
if (windowWidth <= 580) {
/* Clone our navigation */
var mainNavigation = $('nav.main-navigation').clone();
/* Replace unordered list with a "select" element to be populated with options, and create a variable to select our new empty option menu */
$('nav.main-navigation').html('<select class="menu"></select>');
var selectMenu = $('select.menu');
/* Navigate our nav clone for information needed to populate options */
$(mainNavigation).children('ul').children('li').each(function () {
/* Get top-level link and text */
var href = $(this).children('a').attr('href');
var text = $(this).children('a').text();
/* Append this option to our "select" */
$(selectMenu).append('<option value="' + href + '">' + text + '</option>');
/* Check for "children" and navigate for more options if they exist */
if ($(this).children('ul').length > 0) {
$(this).children('ul').children('li').each(function () {
/* Get child-level link and text */
var href2 = $(this).children('a').attr('href');
var text2 = $(this).children('a').text();
/* Append this option to our "select" */
$(selectMenu).append('<option value="' + href2 + '">--- ' + text2 + '</option>');
});
}
});
}
/* When our select menu is changed, change the window location to match the value of the selected option. */
$(selectMenu).change(function () {
location = this.options[this.selectedIndex].value;
});
});
});
