从阵列数据动态地创建一个选择框 [英] Creating a select box dynamically with data from array

问题描述

我想创建动态数据一个选择框是一个数组中，我尝试观看一些JSON教程，但还是有一些麻烦。

i am trying to create a select box dynamically with data that is within an array, I tried watching some JSON tutorials, yet having some trouble still.

 var clothes = [
     Red Dress:"reddress.png",
     Blue Dress:"bluedress.png",
     Black Hair Pin:"hairpin.png"
 ];

 var select = '<select id="clothing_options">';
 for(var i=0;i<clothes.length;i++)
 {
     select +='<option value="'+secondPart[i]+'">'+firstPart[i]+'</option>';
 }

 $('#select_box_wrapper').append(select+'</select>');

 $('#clothing_options').change(function() {
     var image_src = $(this).val();
     $('#clothing_image').attr('src','http://www.imagehosting.com/'+image_src);
 });

你可以看到code未充分发挥作用，因为它是不正确写入。如何从第二部分和从第一部分中的选项的文本获得的值的数据？基本HTML应该是这样的。

as you can see code is not fully functioning because it is not written correctly. How do I get the data for value from the second part and the option text from the first part? basically html should look like this

   <select id="clothing_options">
      <option value="reddress.png">Red Dress</option>
      <option value="bluedress.png">Blue Dress</option>
      <option value="hairpin.png">Black Hair Pin</option>
   </select>

感谢任何解释或建议。只是希望这个code的工作，因为我只是在做这些codeS教训为我自己

thanks for any explanations or suggestions. Just want this code to work, as I am just doing these codes for lessons for myself

推荐答案

您可以将您的阵列更改为JSON对象。

You could change your array to a JSON object..

var clothes = {
 "Red Dress":"reddress.png",
 "Blue Dress":"bluedress.png",
 "Black Hair Pin":"hairpin.png"
};

然后迭代变得更加容易。

and then iteration becomes easier..

for(var item in clothes)
{
  $('<option value="'+item+'">'+clothes[item]+'</option>').appendTo('#clothing_options');
}

这里是HTML：

Here's the HTML:

<div id="select_box_wrapper">
  <select id="clothing_options"></select>
</div>
