PHP开发的一个小小项目，记录下实现思路（附上实现功能的示例代码）（二）

<a href="javascript:del2({$vo['Stu_number']})"
onclick='return del();'>
<img src="__PUBLIC__/Images/xxx" ><a/>
<script>
function del2(Number_stu){
var url="__URL__/delete2";
$.post(url, {Number_stu:Number_stu,select:'1'}, function(msg){
if(msg.info == 'ok') {
alert('删除成功');
window.location.reload();//删除成功后刷新本页面
} else {
alert('删除失败');
}
}, 'json')
}
</script>

<input type="button" class="submit2 btn btn-primary" name="Submit2" onclick="frmSubmit2(this.form)" value="删除"/>

<script>
function frmSubmit2(form){
var checkChild = document.getElementsByClassName('checkChild');  //获取信息用于判断

var j=0;
for(var i=0;i<checkChild.length;i++){
if (checkChild[i].checked!=false) {
j++;
}
}
if (j!=0) {     //未选中信息直接点删除，则提示未选中信息
if(confirm("确定要删除吗？ ")) {
form.action = "__URL__/delete3";
form.submit();
}else{
return ;
}
}else{
alert('未选中信息');
}

}
</script>
