今天做的项目要用到多选的下拉框,开始想在网上找一个插件用用,可是,网上的插件看起来都比较杂乱,我参考了网上的一些插件,自己用jquery写了一个多选下拉框,js写得比较简洁。代码如下。

js代码

复制代码 代码如下:

(function(){
$.fn.extend({
checks_select: function(options){
jq_checks_select = null;
$(this).click(function(e){
jq_check = $(this);
//jq_check.attr("class", "");
if (jq_checks_select == null) {
jq_checks_select = $("
").insertAfter(jq_check);
$.each(options, function(i, n){
check_div=$("
" + n + "
").appendTo(jq_checks_select);
check_box=check_div.children();
check_box.click(function(e){
//jq_check.attr("value",$(this).attr("value") );

temp="";
$("input:checked").each(function(i){
if(i==0){
temp=$(this).attr("value");
}else{
temp+="、"+$(this).attr("value");
}
});
jq_check.attr("value",temp);
e.stopPropagation();
});
});
}else{
jq_checks_select.toggle();

}
e.stopPropagation();
});
$(document).click(function () {
jq_checks_select.hide();
});
//$(this).blur(function(){
//jq_checks_select.css("visibility","hidden");
//alert();
//});
}
})

})(jQuery);
