Jquery与Bootstrap实现后台管理页面增删改查功能示例

时间:2017-03-11 21:29 来源:网管之家整理 字体:[ ] 评论:

使用jquery与bootstrap实现了一个比较简单但功能齐全的增删改查功能的后台管理页面,虽然只是一个CRUD页面,但麻雀虽小五脏俱全,JS常用的功能都用到了,本例用原生的jquery与bootstrap配合使用,不考虑JS的重构性及打包,该例子零耦合,开箱即用。

先看Demo:

一、用到的Jquery功能

1、获取/赋值input输入值

$("#my_id").val();// 获取
$("#my_id").val(“user_id");// 赋值

2、获取/赋值textarea文本域输入值

$("#my_textarea").val();// 获取
$("#my_textarea").val("my_textarea");// 赋值

// 文本域显示默认值,这个和input不一样,不能通过value赋默认值
<textarea name="my_textarea" readonly="true"style="width:100px;height:30px;">这里是文本域默认的内容</textarea>

3、隐藏/显示输入框

$("#my_input").hide();
$("#my_input").show();

4、获取表单form输入的数据

$("#my_input").hide();
$("#my_input").show();

二、示例代码

示例前端active_list.html代码:

<!DOCTYPE html>
<html>
<head>
  <meta charset="gb2312">
  <title>活动列表</title>
  <link href="http://libs.baidu.com/bootstrap/3.0.3/css/bootstrap.min.css" rel="stylesheet">

  {
    //document.getElementById("img_view"+n).src = img_url;
    //document.getElementById("img_view"+n).style.display = '';
    //document.getElementById("img_url"+n).value = img_url;
    $("#img_url"+n).val(img_url);
    $("#img_view"+n).attr('src', img_url);
  }

  function act_resize_img(imgObj, rectWidth, rectHeight, fixIeBug)
  {
    try
    {
      if(!fixIeBug) fixIeBug = true;
      //修正在IE运行下的问题
      if( (imgObj.width==0 || imgObj.height==0) && fixIeBug ) {
        var timer = setInterval(function(){
          act_resize_img(imgObj, rectWidth, rectHeight, false);
          clearInterval(timer);
        }, 1000);
        return;
      }
      var x = imgObj.width>rectWidth ? rectWidth : imgObj.width;
      var y = imgObj.height>rectHeight ? rectHeight : imgObj.height;
      var scale  = imgObj.width/imgObj.height;

      if( x>y*scale ) {
        imgObj.width  = Math.floor(y*scale);
        imgObj.height  = y;
