我有以下 javascript 代码给我下拉菜单。我不希望它下拉菜单。我希望它默认显示所有菜单我应该删除什么。请帮忙。
function DropDown(el) {
this.dd = el;
this.placeholder = this.dd.children('span');
this.opts = this.dd.find('ul.dropdown > li');
this.val = '';
this.index = -1;
this.initEvents();
}
DropDown.prototype = {
initEvents: function () {
var obj = this;
obj.dd.on('click', function (event) {
$(this).toggleClass('active');
return false;
});
obj.opts.on('click', function () {
var opt = $(this);
obj.val = opt.text();
obj.index = opt.index();
obj.placeholder.text(obj.val);
});
},
getValue: function () {
return this.val;
},
getIndex: function () {
return this.index;
}
}
$(function () {
var dd = new DropDown($('#dd'));
$(document).click(function () {
// all dropdowns
$('.wrapper-dropdown-3').removeClass('active');
});
});
