Question

我试图从div中获取一些JSON，其中一部分可以使用，但另一部分不会。

＆＃13;

function downloadURL(){
var curseDom = 'http://www.curse.com/mc-mods/minecraft/';
var submittedURL = $('#download').val();
var domCheck = submittedURL.substring(0,39);
var getJSON = submittedURL.replace("http://www.curse.com/mc-mods/minecraft/", "http://widget.mcf.li/mc-mods/minecraft/") + ".json";
if(domCheck === curseDom){
urls = [];
urls.push(getJSON);
$(urls).each(function(i, item){
  $.get(item, function(data){
    if (typeof data === "object") {
      data = JSON.stringify(data);
    }
    $("#output").append(data).append('<hr>');
  });
});
//Show the mod version selection div
$(".hide1").show();
}else 
//Will move to a more suitable place for user
$("#output").append("Invalid URL");
}
//Refresh Selector to be able to show jar versions with URLs as values
function refreshSelector(){
var text = document.getElementById("output").textContent;
//JSON parse
var obj = jQuery.parseJSON(text);	
//Add version selector
var $select = $('#mySelectID');
$(obj).each(function (index, o) {    
    var $option = $("<option/>").attr("value", o.url).text(o.name);
    $select.append($option);
});
}

//Time to make a new JSON
//Get the output of the modpack JSON
function addToJSON(){
var text = document.getElementById("output").textContent;
//JSON parse
var obj = jQuery.parseJSON(text);	
//Get the pack title?
var modtitle = obj.title;
//Make modpack title (and version, at a later date, visible to the user)
$("#see").append(modtitle + "<br>");
//Remove the previous mod JSON
$( "#output" ).empty();
//Hide this div again
$(".hide1").hide();
}

＆＃13;

                                        <!-- Pack Tool -->       
            <p> <input type="text" name="download" id="download" placeholder="Download URL"></p>

             <!-- Div hidden by default, will show when a URL has been added --> <select id="mySelectID" name="select" class="main-form">
    <option value="">None Selected</option>
</select>
             <button onclick="addToJSON()">Add to Modpack</button>
             </div>              
             <div id="output"><!-- Example of what a JSON in this div will look like -->

我在输出div中添加了一个JSON，这样你就可以看到我想要从中获取什么。

我所拥有的代码将在＆＃34;中看到＆＃34;中显示修改标题。 DIV。但是，选择器代码不起作用。因为它应该添加如下内容：

<option value="http://curse.com/mc-mods/minecraft/224791-blood-magic/2264826">BloodMagic-1.7.10-1.3.3-17.jar</option>

但它并没有添加任何东西。但是，我知道JSON正被解析为＆＃34; obj.title＆＃34; （在示例中＆＃34; Blood Magic＆＃34;被添加到div＆＃34;请参阅＆＃34;）

Answer 1

需要添加：

obj.versions["XXXX"];

然后调用版本而不是obj

var obj2 = obj.versions["XXXX"];
$(obj2).each(function (index, o) {

jQuery - 无法获得JSON的一些元素
