This time I will bring you a case analysis of using the selectpicker drop-down box. What are the precautions when using the selectpicker drop-down box? The following is a practical case, let's take a look.

Preface

I have been using some things from bootstrap recently and wrote a few blogs to record them. . . .

bootstrap selectpicker is a relatively simple drop-down box component in bootstrap. The effect is as follows:

##Attached is the official website api link, http:// silviomoreto.github.io/bootstrap-select/.

The basic operations for using drop-down boxes are generally: single selection, multiple selection, fuzzy

search, dynamic assignment, etc. Let’s see how Usage:

The usage method is as follows

1. The css and js that need to be introduced first:

bootstrap.css
bootstrap-select.min.css

jquery-1.11.3.min.js bootstrap.min.js
bootstrap-select. min.js

2. The js code is as follows:

$(function() { 
  $(".selectpicker").selectpicker({ 
   noneSelectedText : '请选择'//默认显示内容 
  });

Copy after login

//数据赋值 
var select = $("#slpk"); 
select.append("<option value=&#39;1&#39;>香蕉</option>"); 
select.append("<option value=&#39;2&#39;>苹果</option>"); 
select.append("<option value=&#39;3&#39;>橘子</option>"); 
select.append("<option value=&#39;4&#39;>石榴</option>"); 
select.append("<option value=&#39;5&#39;>棒棒糖</option>"); 
select.append("<option value=&#39;6&#39;>桃子</option>"); 
select.append("<option value=&#39;7&#39;>陶子</option>");

Copy after login

//初始化刷新数据 
 $(window).on('load', function() { 
  $('.selectpicker').selectpicker('refresh'); 
 }); 
});

Copy after login

3. jsp content:

<select id="slpk" class="selectpicker" data-live-search="true" multiple></select>

Copy after login

Settings When multiple is used, it is multi-selection. When data-live-search="true", the fuzzy search box is displayed. When it is not set or equal to false, it is not displayed.

4. Other methods:

Get the selected item:

var selectedValues = [];  
slpk:selected").each(function(){ 
selectedValues.push($(this).val()); 
});

Copy after login

Select the specified item (used for editing echo):

# selectpicker').selectpicker('val', arr);

5. Attached is my source code. The drop-down data is obtained from the background through ajax:

$(function() { 
  $(".selectpicker").selectpicker({ 
   noneSelectedText : '请选择' 
  }); 
  $(window).on('load', function() { 
   $('.selectpicker').selectpicker('val', ''); 
   $('.selectpicker').selectpicker('refresh'); 
  }); 
  //下拉数据加载 
  $.ajax({ 
   type : 'get', 
   url : basePath + "/lictran/tranStation/loadRoadForTranStationDetail", 
   dataType : 'json', 
   success : function(datas) {//返回list数据并循环获取 
    var select = $("#slpk"); 
    for (var i = 0; i < datas.length; i++) { 
     select.append("<option value=&#39;"+datas[i].ROAD_CODE+"&#39;>" 
       + datas[i].ROAD_NAME + "</option>"); 
    } 
    $('.selectpicker').selectpicker('val', ''); 
    $('.selectpicker').selectpicker('refresh'); 
   } 
  }); 
 });

Copy after login
