JQuery 级联（ul仿select级联）

2025-01-02 技术教程

功能：【Juqery级联（ul仿select级联）】

说明：最近做一个网站项目遇到的问题,需要美化select,所以就用ul模拟select, 之后就遇到个大问题了，就是要级联，select的话还好级联，现在是ul，所以级联就非常麻烦了.....需要实现：数组，循环，取值，赋值，清值，等等..

Jquery代码：

$(document).ready(function(){

$('.select_box').mouseleave(function(){

$(".son_Ul").hide();

});

$('.select_box span').click(function(){ //鼠标移动函数

$('.son_Ul').hide(); //初始ul隐藏

$(this).parent().find('ul.son_Ul').show(); //找到ul.son_Ul显示

$(this).parent().find('li').hover(function(){

$(this).addClass('hover')},function(){$(this).removeClass('hover')}); //li的hover效果

$(this).parent().click(function(){},

function(){

$(this).parent().find("ul.son_Ul").hide();

}

);

},function(){}

);

$('ul.son_Ul li').click(function(){

$(this).parents('li').find('span').html($(this).html());

$(this).parents('li').find('ul').hide();

});
