前端js 判断输入的必须是数字,判断金钱

//输入的必须是数字
$(".xzjl").on("keyup", ".num", function () {
var v = $(this).val();
if (v == 0 || v.length == 0) {
v = 0;
}
else {
v = v.replace(/[^\d]/g, '');
}
$(this).val(v);
});

function check() {
//判断金钱
var amount = $.trim($("#txtAmount").val());
var regex = /^(([+]?\d*$)|(^[+]?\d+(\.\d+)?$))/;
if (amount != "") {
if (!regex.test(amount)) {
$("#txtAmount").val("0.00");
}
}
}

eg:

<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server">
<script type="text/javascript">
$(function () {
//输入的是数字
$(".xzjl").on("keyup", ".num", function () {
var v = $(this).val();
if (v == 0 || v.length == 0) {
v = 0;
}
else {
v = v.replace(/[^\d]/g, '');
}
$(this).val(v);
});
});

function check() {
var f = true;
$("#tab_2 tr textarea").each(function () {
var txt = $(this).val();
if (txt.length == 0) {
f = false;
}
});
return f;
}

function sub() {
var f = check();
if (f) {
var data = getTxt();
var para = { t: 6, data: data };
var ajaxUrl = "/Handler/cbk/RequstHelper.ashx";
$.ajax({
url: ajaxUrl,
type: "Post",
dataType: "json",
async: false,
data: para,
success: function (data) {
var r = eval(data);
if (r == "1") {
art.dialog.alert("添加成功");
}
if (r == "2") {
art.dialog.alert("本周已经提交过");
}
else {
art.dialog.alert("系统出现异常！");
}
}
})
}
else {
art.dialog.alert("请填完整所有内容");
}
}

function getTxt() {
var list = "";
$("#tab_2 tr").each(function () {
//var len = $("#tab_2 tr").length;
var subject = $(this).find(".sp").text();
var num = $(this).find(".num").val();
var levelSatisfy = $(this).find('option:selected').val();
var PersonQue = $(this).find('.txt1').val();
var JishuQue = $(this).find('.txt2').val();
var CompanyQue = $(this).find('.txt3').val();
var WeekPlan = $(this).find('.txt4').val();

list += subject + "," + num + "," + levelSatisfy + "," + PersonQue + "," + JishuQue + "," + CompanyQue + "," + WeekPlan + "|";
});
return list;
}
