jquery+正则实现统一的表单验证

<input type="text" datatype=“正则”/>

//表单验证
//点击下一步事件
function checkForm(form){
var success = true;
$("."+form+" input").each(function(){
var $that = $(this);
var dataType = eval($that.attr("dataType"));
if(dataType!=undefined){
if($that.val().match(dataType)){
$that.removeClass("borderRed");
}else{
$that.focus();
$that.addClass("borderRed");
success = false;
return false;
}
}
})
return success;
}

//给每个带有datatype属性的标签绑定blur focus事件

$(document).on("blur","input",function(){
var $that = $(this);
var dataType = eval($that.attr("dataType"));
if(dataType!=undefined){
if($that.val().match(dataType)){
$that.removeClass("borderRed");
}else{
$that.addClass("borderRed");
}
}
})
$(document).on("focus","input",function(){
$(this).removeClass("borderRed");
});
