bootstrap实现弹窗和拖动效果_javascript技巧-js教程-PHP中文网

有时开发一些特效，自己感觉挺爽的，像操作自己电脑一样操作你的网页，这里就介绍一个使用bootstrap的一点多窗口和拖动效果吧！

这里，我们不使用静态打开的的方式，low...,1、添加一个a链接触发，打开按钮;2、编写动态打开js脚本; 3、编写modal中间内容;4、添加拖动效果;5、打开多个modal , 调用dragModal(new Array('modalId1','modalId2'));

1、添加一个a链接触发，打开按钮：

<a href="javascript:;" title="开关" class="open-modal-dynamic" url="index.php&#63;m=index&c=cc&a=aa&id=22" alert='1' divid="editModal">打开modal<a>
<div id="addModal" class="modal hide fade" style="max-width:800px;" data-backdrop="static"></div>  <!-- 打开容器 -->

2、编写动态打开js脚本：

//打开弹窗
  $('.open-modal-dynamic').on('click', function(){
    var modalId = $(this).attr('divid') &#63; $(this).attr('divid') : 'Modal', url = $(this).attr('url');
    $.get(url, function(data){
      if(data.status == 1){
        //禁止选择文字，在拖动时会有影响
        $('html').off('selectstart').on('selectstart', function(){return false;});
        $('#' + modalId).html(data.htmlData);
        $('#' + modalId).modal({'show':true});
      }else{
        alert(data.info);
      }
    }, 'json');

3、编写modal中间内容：

<style>
  .line{margin-bottom: 5px;}
  .line .left{width: 100px;text-align:right;display:block;}
  .form-button{padding:2px 10px;background:#73A86A;color:#ffffff;border:none;}
  .form-button:hover{background:#146206;}
</style>
<div class="modal-header">
  <a class="close" title="关闭小窗口" data-dismiss="modal">×</a>
  <h3>modal window<h3>
</div>
<div class="modal-body" style="padding-bottom: 5px;">
  <div class="line">
    <span class="left">脚本名称：</span>
    <span>
   <select name="name">
  <option value='11'>11</option>
   <option value='22'>22</option>
    </select>
    </span>
  </div>
  <div class="line">
    <span class="left">日期：</span>
    <span style="word-break:break-all;" title="的时间">
      <input class="Wdate ipt date-picker" style="width: 100px;margin: 0;" type="text" id="date_add" value="" />
    </span>
  </div>
  <div class="line" title="设置">
    <span class="left">是否停止：</span>
    <span>
      <label><input type="radio" name="is_del_add" value="1" />强制停止</label>
      <label><input type="radio" name="is_del_add" value="0" />正常处理</label>
    </span>
  </div>
  <div class="line" title="按照实际情况允许进行模拟更改">
    <span class="left">执行情况：</span>
    <span>
      <label><input type="radio" name="status_add" value="5" onclick="javascript:return confirm('你确定要操作该状态吗，这是系统的操作，请确认？');" />11</label>
      <label><input type="radio" name="status_add" value="1" onclick="javascript:return confirm('你确定要操作该状态吗，这是系统的操作，请确认？');" />22成</label>
      <label><input type="radio" onclick="javascript:return confirm('你确定要操作该状态吗，这是系统的操作，请确认？');" name="status_add" value="2"/>223行</label>
      <label><input type="radio" onclick="javascript:return confirm('你确定要操作该状态吗，这是系统的操作，请确认？');" name="status_add" value="0" />445</label>
      <label><input type="radio" onclick="javascript:return confirm('你确定要操作该状态吗，这是系统的操作，请确认？');" name="status_add" value="4"  />55失败</label>
    </span>
  </div>
  <div class="line">
    <span>操作说明：</span>
    <textarea name="memo" id="memo" cols="100" rows="1" style="width:370px;></textarea>
  </div>
  <div class="line" style="text-align:center;">
    <input type="button" value="提交" class="form-button" id="submit2" />
    <input type="hidden" id="id_add" value="22" />
  </div>
</div>
<div class="modal-footer">
  <span class="loading"></span>
  <button class="btn" data-dismiss="modal" aria-hidden="true">关闭</button>
</div>
<script src="/js/dragModal.js"></script>
<script>
  $(function(){
    $('#submit2').off().on('click', function(){
      var status = $('input[name=status_add]:checked').val(),
          memo = $('#memo').val(),
          id = parseInt($('#id_add').val()),
          is_del = $('input[name=del_add]:checked').val(),
          cron_name = $('#name_add').val(),
          cron_date = $('#date_add').val(),
          url ='index.php&#63;m=xx&c=xx&a=';
      if(!memo){
        alert('请填写操作备注，如不处理，请直接关闭对话框！');
        return false;
      }
      $.post(url, {status: status, cron_name:cron_name, memo: memo, id: id, cron_date: cron_date, is_del: is_del}, function(data){
        if(data.status == 1){
          alert(data.info);
          window.location.reload();
        }else{
          alert(data.info);
        }
      }, 'json')
    });
 
  });
  //  drag effects begin, define the global variables to receive the changes,because of the different function of the modal
    dragModal('editModal');
</script>

4、添加拖动效果：

var clicked = "0";
var dif = {};
;function dragModal(obj) {
 
  if(clicked == undefined || obj == undefined || dif == undefined){
    return false;
  }
  if(typeof obj == 'string')
  {
    obj = new Array(obj);
  }
  var modalNums = obj.length;
  //drag effects begin
  var i = 0;
  for (i = 0; i < modalNums; i++) {
    dif[obj[i]] = {'difx': 0, 'dify': 0};
  }
  $("html").off('mousemove').on('mousemove', function (event) {
    if (clicked == "0") {
      for (i = 0; i < modalNums; i++) {
        dif[obj[i]].difx = event.pageX - $("#" + obj[i]).offset().left;
        dif[obj[i]].dify = event.pageY - $("#" + obj[i]).offset().top;
      }
    }
    if (clicked > 0 && clicked <= modalNums) {
      var clickedObj = obj[clicked - 1];
      var newx = event.pageX - dif[clickedObj].difx - $("#" + clickedObj).css("marginLeft").replace('px', '');
      var newy = event.pageY - dif[clickedObj].dify - $("#" + clickedObj).css("marginTop").replace('px', '');
      $("#" + clickedObj).css({top: newy, left: newx});
    }
 
  });
 
  $("html").off('mouseup').on('mouseup', function (event) {
    clicked = "0";
  });
 
  for(i = 0; i < modalNums; i++){
    //注重此处不能直接传入i值，此处即为添加多窗口时的效果使用
    $("#" + obj[i] + " .modal-header").off().on('mousedown',{index: i}, function (event) {
      clicked = event.data.index + 1;
    });
    $("#" + obj[i] + " .modal-footer").off().on('mousedown', {index: i}, function (event) {
      clicked = event.data.index + 1;
    });
    $('#' + obj[i]).on('hide.bs.modal', function () {    //关闭时打开选中
      $('html').off('selectstart').on('selectstart', function () {
        return true;
      });
    });
 
  }
}

5、打开多个modal , 调用dragModal(new Array('modalId1','modalId2'));

整个过程即是如此，有需要的，就参考参考吧！
