动态增删改Table表格
一、用js做的表格动态增删查改
工具JavaScript:util.js
- //全选反选
- function checkAll(boxName) {
- var checkBox = document.getElementsByName(boxName);
- for (i = 0; i < checkBox.length; i++) {
- var checked = checkBox[i].checked;
- if (checked) {
- checkBox[i].checked = false;
- } else {
- checkBox[i].checked = true;
- }
- }
- }
- //多选验证
- function multiCheck(idArray)
- {
- //var idArray = document.getElementsByName(boxName);
- var count = 0;
- for(i=0;i<idArray.length;i++)
- {
- if(idArray[i].checked)
- {
- count++;
- }
- }
- return count;
- }
- //回车切换焦点
- function toNext(next)
- {
- if(event.keyCode==13)
- {
- next.focus();
- }
- }
- //打开右键菜单
- function openShortCutMenu(oRow)
- {
- // 选中当前行
- SelectRow(oRow);
- aOpenPopMenu("ShortCutMenu");
- event.cancelBubble = true;
- event.returnValue = false;
- }
- //关闭右键菜单
- function CloseShortCutMenu(){
- aClosePopMenu("ShortCutMenu");
- }
- //显示右键菜单
- function aOpenPopMenu(MenuId){
- if (document.all(MenuId)){
- document.all(MenuId).style.left = event.clientX + document.body.scrollLeft;
- document.all(MenuId).style.top = event.clientY + document.body.scrollTop;
- document.all(MenuId).style.display = "";
- }
- }
- //隐藏右键菜单
- function aClosePopMenu(MenuId){
- if (document.all(MenuId)){
- document.all(MenuId).style.display = "none";
- }
- }

- }else
- {
- for(i=0;i<stuValues.length;i++)

- <script>init();</script>

二、在学习和做项目过程中写的JavaScript验证函数(正则表达式)
- //身份证合法性
- function isIdentity(new_num)
- {
- var num = new_num;
- var len = num.length ;
- var re ;
- if (len == 15)
- {
- if (isNaN(num)) {alert("输入的不是数字!"); return false;}
- }
- if (len == 15)
- re = new RegExp(/^(\d{6})()?(\d{2})(\d{2})(\d{2})(\d{3})$/);
- else if (len == 18)
- re = new RegExp(/^(\d{6})()?(\d{4})(\d{2})(\d{2})(\d{3})(\d|[X])$/);
- else { alert("输入的数字位数不对!"); return false;}
- var a = num.match(re);
- if (a != null)
- {
- if (len==15)
- {
- var D = new Date("19"+a[3]+"/"+a[4]+"/"+a[5]);
- var B = D.getYear()==a[3]&&(D.getMonth()+1)==a[4]&&D.getDate()==a[5];
- }
- else
- {
- var D = new Date(a[3]+"/"+a[4]+"/"+a[5]);
- var B = D.getFullYear()==a[3]&&(D.getMonth()+1)==a[4]&&D.getDate()==a[5];
- }
- if (!B) {alert("输入的身份证号 "+ a[0] +" 里出生日期不对!"); return false;}
- }else
- {
- alert("输入的身份证号不对!");
- return false;
- }
- return true;
- }
- //电子邮箱的合法性
- function checkemail(email)
- {
- var myReg = /^([-_A-Za-z0-9\.]+)@([_A-Za-z0-9]+\.)+[A-Za-z0-9]{2,3}$/;
- if(!myReg.test( email ))
- {
- alert("请输入合法的电子邮件地址");
- return false;
- }
- return true;
- }
- //验证邮政编码
- function checkPostcode(postcode)
- {
- var reobj = new RegExp(/^\d+$/);
- if(!reobj.test(postcode)||!postcode.length!=6)
- {
- alert("请输入正确的邮政编码");
- return false;
- }
- return true;
- }
- //价格验证
- function checkPrice(price)
- {
- var float = /^\d+(.){0,1}?\d{0,2}$/;//两位小数
- var int = /^[1-9]\d*$/;//正整数
- if(!float.test(price)&&!int.test(price))
- {
- alert("请输入正确的商品价格");
- return false;
- }
- return true;
- }
- //验证上传图片类型
- function valiImgType(fileName)
- {
- var extension = fileName.substring(fileName.lastIndexOf(".")+1,fileName.length).toLowerCase();
- if(extension!="jpg"&&extension!="gif")
- {
- alert("请选择jpg或gif格式的图片");
- return false;
- }
- return true;
- }
- //验证是否为中文
- function iszhCN(name)
- {
- var Expression=/[^\u4E00-\u9FA5]/;
- var objExp=new RegExp(Expression);
- if(!/^[\u4e00-\u9fa5]+$/.test(name))
- {
- alert("请输入汉字,验证未通过");
- return false;
- }
- return true;
- }
- //验证IP地址
- function checkIP(sIPAddress)
- {
- var exp=/^(\d{1,2}|1\d\d|2[0-4]\d|25[0-5])\.(\d{1,2}|1\d\d|2[0-4]\d|25[0-5])\.(\d{1,2}|1\d\d|2[0-4]\d|25[0-5])\.(\d{1,2}|1\d\d|2[0-4]\d|25[0-5])$/;
- var reg = sIPAddress.match(exp);
- var ErrMsg="你输入的是一个非法的IP地址段!\nIP段为::xxx.xxx.xxx.xxx(xxx为0-255)!"
- if(reg==null)
- {
- alert(ErrMsg);
- return false;
- }
- return true;
- }
三、在学习和做项目过程中写的常用JavaScript函数
- //四舍五入,保留valiNumber个小数;
- function round(number,valiNumber)
- {
- document.write(number.toFixed(valiNumber));
- }
- // 判断字符串长度,一个中文按两个字符算
- function strlen(str)
- {
- var len;
- var i;
- len = 0;
- for (i=0;i<str.length;i++)
- {
- if (str.charCodeAt(i)>255) len+=2; else len++;
- }
- return len;
- }
四、用JavaScript限制html输入框为整数
- <!-- 第一种 -->
- <input onkeypress="return event.keyCode>=48&&event.keyCode<=57"
- onpaste="var s=clipboardData.getData('text'); if(!/\D/.test(s)) value=s.replace(/^0*/,'');return false;"
- onkeyup="if(/(^0+)/.test(value))value=value.replace(/^0*/, '')" />
- <!-- 第二种 -->
- <input type="text" onkeyup="this.value=this.value.replace(/\D/g,'');">
