由于ajax表，行Onlick功能无法正常工作

标签： javascript php jquery mysql ajax

我现在能够显示我的表，因为我使用ajax将我的php文件中的表回显到我的html索引文件中。但现在，我需要显示一个警告onclick，它会告诉我接下来几列的值。我想点击课程，它会告诉我警报中未来几个季度的申请人数量（通过javascript功能）。

索引：

function gettable(string,strings)
        {

var a=string;
var b=strings;
if(a == null && b == null)
{
a = new Date().getFullYear();
b = "";
}

    if (window.XMLHttpRequest) {
        // code for IE7+, Firefox, Chrome, Opera, Safari
        var xmlhttp = new XMLHttpRequest();
    } else {
        // code for IE6, IE5
        var xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
    }
    xmlhttp.onreadystatechange = function() {
        if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
            document.getElementById("inputtable").innerHTML = xmlhttp.responseText;

        }
    };

    xmlhttp.open("GET","gettabledata.php?q="+a+"&v="+b,true);
    xmlhttp.send();
        }

var name;
$(document).ready(function()
{
$('#table tr #abc').on('click', function(){

    name = $(this).text();
    alert(name);
});
})

gettabledata.php（我回显我的表的文件）：

    <?php

error_reporting(0);
$q = intval($_GET['q']);
$v = $_GET['v'];



if ($q=="")
{$i=date("Y");}
else
{
    $i=$q;
}
$i0=$i.'-01-01';

$i1=$i.'-03-31';
$i2=$i.'-06-31';
$i3=$i.'-09-31';
$i4=$i.'-12-31';

echo "<table id='table' class='clickable-row' border='1' style='width:100%'>

答案 0 :(得分：0)

id='table'在您的代码中是重复的。请从id = "table"删除tr。

您需要修改onClick函数，如... 

$('#inputtable').on('click', '#table tr #abc',function(){

我的事。它对你有帮助....
