按值属性使用jQuery排序选择选项 [英] Sort Select Options by Value Attribute Using jQuery

问题描述

好吧，标题说明了一切。我正在做的是创建一个特色产品模块。大小的下拉列表使用JSON填充，我使用句柄来呈现html。我无法控制JSON文件。我尝试通过选项标签中的实际文本对选项值进行排序，但是我意识到选项值在此之后是错误的。所以现在我试图按照他们的价值属性对选项进行排序，但还没有弄清楚。我试图做这样的事情：

  var selectList = $（'＃featuredSelectField option'）; 
 var newList = []; 
 var theNewNew = []; 
 for（var i = 0; i< selectList.length; i ++）{
 newList [i] =（selectList [i] .value）; 
} 
 newList.sort（）; 
 for（var i = 0; i  theNewNew [i] = $（'＃featuredSelectField option [value =''+ newList [i] +']'' ）; 
 selectList [i] = theNewNew [i]; 
} 
  

这里是html：

 < select id =featuredSelectFieldname =addid7617843size =1> 
< option value =data-value =>选择一个选项< / option> 
< option value =10493640data-value =10493640data-qty =30data-mxqty =30>大小5.5  -  $ 111.99< / option> 
< option value =10493639data-value =10493639data-qty =120data-mxqty =50>大小5  -  $ 111.99< / option>

< option value =11288830data-value =11288830data-qty =1data-mxqty =1>大小4.5  -  $ 111.99< / option> 
< option value =10493645data-value =10493645data-qty =51data-mxqty =50>大小7.5  -  $ 111.99< / option> 
< option value =10792503data-value =10792503data-qty =5data-mxqty =5>大小9.5  -  $ 111.99< / option> 
< option value =11288831data-value =11288831data-qty =6data-mxqty =6>大小4  -  $ 111.99< / option> 
< / select> 
  

解决方案

  var selectList = $（'＃featuredSelectField选项'）; 
 $ b $ selectList.sort（function（a，b）{
a = a.value; 
b = b.value; 
 
 return ab; 
}）; 
 
 $（'＃featuredSelectField'）。html（selectList）;

Well, the title says it all. What I am doing is creating a featured product module. The drop down list of sizes is populated using JSON and I am using handlebars to render the html. I do not have control over the JSON file. I tried sorting the option values by the actual text within the option tags, but I realized that the option values were wrong after that. So now I am trying to sort the options by their value attributes, but haven't figured it out yet. I am trying to do something like this:

var selectList = $('#featuredSelectField option');
var newList = [];
var theNewNew = [];
for(var i=0; i<selectList.length; i++){
    newList[i]=(selectList[i].value);    
}
newList.sort();
for(var i=0; i<newList.length; i++){
    theNewNew[i] = $('#featuredSelectField option[value="'+newList[i]+'"]');
    selectList[i] = theNewNew[i];
}

and here is the html:

<select id="featuredSelectField" name="addid7617843" size="1">
    <option value="" data-value="">Select an option</option>
    <option value="10493640" data-value="10493640" data-qty="30" data-mxqty="30">Size 5.5 - $111.99</option>
    <option value="10493639" data-value="10493639" data-qty="120" data-mxqty="50">Size 5 - $111.99</option>
    <option style="display: none;" disabled="disabled" value="10792504" data-value="10792504" data-qty="0" data-mxqty="0">Size 10 - $111.99 Sold Out</option>
    <option value="10493644" data-value="10493644" data-qty="138" data-mxqty="50">Size 7 - $111.99</option>
    <option value="10493642" data-value="10493642" data-qty="22" data-mxqty="22">Size 6.5 - $111.99</option>                
    <option value="10493641" data-value="10493641" data-qty="57" data-mxqty="50">Size 6 - $111.99</option>              
    <option value="10493648" data-value="10493648" data-qty="99" data-mxqty="50">Size 9 - $111.99</option>      
    <option value="10493647" data-value="10493647" data-qty="28" data-mxqty="28">Size 8.5 - $111.99</option>                
    <option value="10493646" data-value="10493646" data-qty="74" data-mxqty="50">Size 8 - $111.99</option>                  
    <option value="11288830" data-value="11288830" data-qty="1" data-mxqty="1">Size 4.5 - $111.99</option>
    <option value="10493645" data-value="10493645" data-qty="51" data-mxqty="50">Size 7.5 - $111.99</option>                    
    <option value="10792503" data-value="10792503" data-qty="5" data-mxqty="5">Size 9.5 - $111.99</option>
    <option value="11288831" data-value="11288831" data-qty="6" data-mxqty="6">Size 4 - $111.99</option>
</select>

解决方案

var selectList = $('#featuredSelectField option');

selectList.sort(function(a,b){
    a = a.value;
    b = b.value;

    return a-b;
});

$('#featuredSelectField').html(selectList);
