1.验证只能输入数字包括负数
function CkeckData(obj)
{
var inputObj = obj;
var temp = inputObj.value;
if(temp!="")
{
var digit = /^-?\d+(\.\d+)?$/;
if (!digit.test(temp))
{
alert("只能输入负数或数字");
inputObj.focus();
}
}
2.jQuery ajax的基本用法
var username = $("#username").val();
var pwd = $("#userpwd").val();
$.ajax({
type: "post",
async:false,
url: "validate.do?username="+username+"&userpwd="+pwd,
dataType:"text",
success: function(data){
result = data;
}
});
