Bootstrap模态框调用功能实现方法_javascript技巧

近在做一个项目时需要在页面中嵌入弹出窗口，用来展示表单信息。其实这种弹出窗口有很多jquery插件都可以实现，我这边前端都是用Bootstrap的，正好Bootstrap有模态框这个功能，这下就可以直接拿它实现了。

实现步骤如下：

在前端页面引入bootstrap相关的css和js文件

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.2/css/bootstrap.min.css">
<script type='text/javascript' src='../public/js/jquery-1.8.2.min.js'></script>
<script src="http://libs.baidu.com/jquery/1.9.0/jquery.js"></script>
<script src="http://cdn.bootcss.com/bootstrap/2.3.1/js/bootstrap-transition.js"></script>
<script src="http://cdn.bootcss.com/bootstrap/2.3.1/js/bootstrap-modal.js"></script>

然后在html中创建一个button用来点击触发弹出窗口，这里是调用f_show函数并传入一个参数向后端发起Ajax请求，Ajax处理请求后返回前端并输出到模态框。

<td><button type="button" data-toggle="modal" data-target="#myModal" onclick="f_show('<?php echo $row['service_tag'];?>');" ><?php echo $row['service_type'];?></button></td>

Ajax处理请求

<script>
function f_show(tags){
$.ajax({
type:"POST",
url:"service_info_ajax.php",
data: {"tags":tags},
dataType:'json',
success: function(data){
if(data.state == '1'){
$("#service_key").val(data.service_key);
$("#service_comments").val(data.service_comments);
$("#service_help").val(data.service_help);
$("#service_target").val(data.service_target);
$("#service_mail").val(data.service_mail);
$("#service_mailpass").val(data.service_mailpass);
$("#service_date").val(data.service_date);
if(data.service_type <= '2'){
document.getElementById("remark1").style.display = "none";
document.getElementById("remark2").style.display = "none";
document.getElementById("notes1").style.display = "";
document.getElementById("notes2").style.display = "";
$("#notes2").text(data.service_notes);
}else{
document.getElementById("notes1").style.display = "none";
document.getElementById("notes2").style.display = "none";
document.getElementById("remark1").style.display = "";
document.getElementById("remark2").style.display = "";
$("#remark2").text(data.service_remark);
}
}
},
});
}
$('#myModal').modal(options);
</script>

后端处理返回

<?php
require_once("../db.class.php");
require_once("../common.class.php");
require_once("../mailtmp.class.php");
require_once("../admin.class.php");
$obj_comm = new Comm();
$obj_mail = new mailtemplate();
$obj_admin = new AdminSub();
$tags = trim($_POST['tags']);
#$tags = "1643e0cb3d6078a9a0fd86c8239cd4c1";
$tag_arr = $obj_admin->find_service_tag($tags,$db);
if($tag_arr){
$tag_arr['state'] = 1;
echo json_encode($tag_arr);
}
?>

前端模态框页面展示
