复制代码 代码如下:
function getUrlArray(e, type){
var urls = $.trim($("#report_url_list").val());
urls = urls.replace(/s*n+s*/ig,"n");
$("#report_url_list").val(urls);
//format the urls
if(type == "blur"){
reportUrlElm.val(urls);
}
if(e && e.keyCode == 13){
reportUrlElm.val(urls + "n");
}
urls = urls.split("n");
user_urls = urls;
return urls;
}
function checkurls(e, type) {
$("#errorList").find("span").hide();
