常用js/jsonp跨域
判断是否存在某个字符
var url=window.location.href;
var patt = new RegExp('itemid');
if(patt.test(url)){//字符串存在返回true否则返回false
alert(1);
}else{
alert(0);
}
获取属性值:
var username=$(this).attr("abbr");
1. Javascript 返回上一页history.go(-1), 返回两个页面: history.go(-2);
history.back();
页面刷新:
window.location.reload();
页面跳转:
window.location.href="http://zizhi.whxhkj.net/notice/list.php";
AJAX:
function() {
$('.btn').click(function() {
var itemid = $('#itemid').val();
var type = $('input:radio:checked').val();
var company = $('#company').val();
var address = $('#address').val();
var truename = $('#truename').val();
var telephone = $('#telephone').val();
var service = $('#service').val();
//alert(telephone);
if (itemid == 0) {
var data = "itemid=0&type=" + type + "&company=" + company + "&address=" + address + "&truename=" + truename + "&telephone=" + telephone + "&service=" + service;
} else {
var data = "itemid=" + itemid + "&type=" + type + "&company=" + company + "&address=" + address + "&truename=" + truename + "&telephone=" + telephone + "&service=" + service;
}
//alert(data);
$.ajax({
type: 'post',
url: './ajax.php',
data: data,
async: false,
success: function(msg) {
if (msg == 1) {
//alert('修改成功');
//location.reload();
}
},
error: function(msg) {
},
});
