单击按钮时我的模态不会触发。我已经尝试了我所知道的所有可能的方法，并尝试了所有可能的“Hit & Try”方法。所以我回到这个论坛寻求帮助。我的代码如下：-

单击第三列中的 MoD ID 时的函数 .click() 未触发。此列中的行内容如下所示：-
<input type="button" name="AMWP/2017-18/1" value="AMWP/2017-18/1" id="AMWP/2017-18/1" class="btn btn-info btn-xs view_data">
<input type="button" name="AMWP/2017-18/2" value="AMWP/2017-18/2" id="AMWP/2017-18/2" class="btn btn-info btn-xs view_data">
<input type="button" name="AMWP/2017-18/3" value="AMWP/2017-18/3" id="AMWP/2017-18/3" class="btn btn-info btn-xs view_data">
我现在认为这里可能存在处理问题，因为该表正在由 get_value.php 填充到 main.php 中，然后我尝试通过单击 get_value.php 生成的按钮来触发 Modal。
问题在于您尝试在不存在的对象上绑定单击事件。即
$('.view_data').click(...view_data您有两个选择：
1）不要将事件绑定在按钮上，而是绑定在
body$('body').on('click', '.view_data', function(){
alert('clicked ' + $(this).val());
});
2）将结果写入 DOM 后，将事件绑定放入 ajax 调用的 success 方法中
fetchChange();
function fetchChange() {
var finyear = "2017-18";
var cmdname = "HQ TC";
var stnname = "All Stations";
var statusname = "All Status";
var cfaname = "All CFA";
var wkcatname = "All Categories";
$.ajax({
url:"get_value.php",
method:"POST",
data:{finyear:finyear, wkcatname:wkcatname,cmdname:cmdname,stnname:stnname, statusname:statusname,cfaname:cfaname},
success:function(data){
$('#recordsfromraky').html(data);
$('.view_data').click(function(){
var employee_id = $(this).attr("id");
var fired_button = $(this).val();
alert(fired_button);
$('#dataModal').modal("show");
});
}
});
};
}）；
修改后的get_value.php如下：-
<?php
ob_start();
include_once $_SERVER['DOCUMENT_ROOT'] . '/CommandWks/phpAssets/dbconnect.php';
ini_set("xdebug.var_display_max_children", -1);
ini_set("xdebug.var_display_max_data", -1);
ini_set("xdebug.var_display_max_depth", -1);
$finyr = $_POST['finyear'];
$commdname = $_POST['cmdname'];
$stationname = $_POST['stnname'];
$statustype = $_POST['statusname'];
$cfanamed = $_POST['cfaname'];
$catname = $_POST['wkcatname'];
$finyr = str_replace('"', '', $finyr);
$commdname = str_replace('"', '', $commdname);
$stationname = str_replace('"', "'", $stationname);
$statustype = str_replace('"', "", $statustype);
$cfanamed = str_replace('"', '', $cfanamed);
$catname = str_replace('"', '', $catname);

请勿在循环末尾添加 。这也达到了目的。
