Jquery与Bootstrap实现后台管理页面增删改查功能示例
作者:Corwien
本篇文章主要介绍了Jquery与Bootstrap实现后台管理页面增删改查功能示例,具有一定的参考价值,有兴趣的可以了解一下。
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"> <script src="http://libs.baidu.com/jquery/2.0.0/jquery.min.js"></script> <script src="http://libs.baidu.com/bootstrap/3.0.3/js/bootstrap.min.js"></script> <meta name="viewport" content="width=device-width, initial-scale=1.0"> </head> <script> function show_upload_info(img_url,title,n) { //document.getElementById("img_view"+n).src = img_url;

//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);

$("#is_forever").attr("checked","checked"); } else { $("#expire_time").val(data_obj.expire_time); } } else { $("#tip").html("<span style='color:red'>失败,请重试</span>"); // alert('操作失败'); } }, error:function() { alert('请求出错'); }, complete:function() { // $('#tips').hide(); } }); return false; } //点击 活动是否限时事件 function click_forever() { // 不能用attr('checked')获取是否选中,因为返回‘undedied' // var is_check = $('#is_forever').attr('checked');

} } // 提交表单 function check_form() { var title = $.trim($('#title').val()); var tag_name = $.trim($('#tag_name').val()); var act = $.trim($('#act').val()); if(!title) { alert('标题不能为空!'); return false;
