js学习总结----crm客户管理系统之前端页面开发及数据渲染
具体代码如下:
index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
<link rel="stylesheet" href="css/index.css" charset='utf-8'>
</head>
<body>
<div class='box'>
<a href="add.html" class='link'>增加客户</a>
<h2 class='head'>
<span class='w50'>编号</span>
<span class='w150'>姓名</span>
<span class='w50'>年龄</span>
<span class='w200'>电话</span>
<span class='w200'>地址</span>
<span class='w150'>操作</span>
</h2>
<ul class='list' id='list'>
<!-- <li>
<span class='w50'>1</span>
<span class='w150'>xxx</span>
<span class='w50'>25</span>
<span class='w200'>xxxxxxxxx</span>
<span class='w200'>xxxxxxxxxxx</span>
<span class='w150 control'>
<a href="">修改</a>
<a href="">删除</a>
</span>
</li> -->
</ul>
</div>
<script charset='utf-8' type='text/javascript' src='js/ajax.js'></script>
<script charset='utf-8' type='text/javascript'>
var oList = document.getElementById('list');
//首先获取所有的客户信息，完成页面的数据绑定
var customModule = (function(){
//DELETE CUSTOM
function removeCustom(){

var tar = e.target || e.srcElement,
tarTag = tar.tagName.toUpperCase();
if(tarTag==="A" && tar.innerHTML ==="删除"){
var customId = tar.getAttribute("customId");
var flag = window.confirm("确定要删除编号为["+customId+"]的客户吗？");
if(flag){
ajax({
url:"/removeInfo?id="+customId,
success:function(jsonData){
if(jsonData && jsonData.code===0){
oList.removeChild(tar.parentNode.parentNode);
return;
}
alert(jsonData.msg);
}
})
}
}
}
}
//BIND HTML
function bindHTML(data){
var str = "";
for(var i = 0;i<data.length;i++){
var curData = data[i];
str+='<li>';
str+='<span class="w50">'+curData["id"]+'</span>';

str+="</span>"
str+='</li>';
}
oList.innerHTML = str;
}
//SEND AJAX GET DATA
function init(){
ajax({

if(jsonData && jsonData.code==0){
var data = jsonData.data;
bindHTML(data);

}
</script>
</body>
</html>
custom.json(模拟后台数据)
[{"name":"a sd","age":"sa ","phone":"da s","address":"sd ","id":2}]
最终效果：
这个只是一个非常简单的demo，没有很复杂。
