javascript - 如何将 json 值附加到选择列表

Question

[{"key":"0.75","value":"3/4","Default_Value":"0"}, 
 {"key":"0.875","value":"7/8","Default_Value":"1"},
"key":"1.75","value":"1 3/4","Default_Value":"0"}]

我有 json 数组如何将这个 json 有选项附加到选择列表

这里是我想追加的方式

<option value="0.75">3/4</option>
<option value="0.875">7/8</option>
<option value="1.75">1 3/4</option>

如果“Default_Value”:“1”我需要选择默认值我不知道如何迭代和获取值以及如何在选项中显示关键值的痛苦，非常感谢任何帮助。

$("#p_combination").empty();
//supposing that your response object is something like :
var response=[{'dish_name':'3/4','dis-val':0.75},{'dish_name':'7/8','dis-val':0.875},{'dish_name':'1.75','dis-val':1.75}];
for(var i = 0; i < response.length; i++) {
 $("#p_combination").append("<option value='" + response[i]['dis-val'] + "'>" +response[i]['dish_name'] + "</option>");
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.0/jquery.min.js"></script>
<select name="p_combination[]" id="p_combination" multiple>
    <option value="0">Select</option>
</select>

 $arrays=json_decode([{"key":"0.75","value":"3/4","Default_Value":"0"}, 
 {"key":"0.875","value":"7/8","Default_Value":"1"},
"key":"1.75","value":"1 3/4","Default_Value":"0"}]);
foreach($arrays as $array){
$select="";
if($array->Default_Value==1){
$select="selected='selected'";
}
echo '<option '.$select.' value="'.$array->value.'">'.$array->value.'</option>';
}
