jQuery从单个和多个标签解析xml [英] jquery parse xml from single and multiple tags

问题描述

遇到了从xml节点返回文本的问题.所有这一切都必须是动态的.这是xml:

Got a problem returning the text from an xml node. It all needs to be dynamic. Here is the xml:

<instructions>Some ins text.</instructions>
<options>
    <option>1.png</option>
    <option>2.png</option>
    <option>3.png</option>
    <option>4.png</option>
</options>
<noOfOptions>4</noOfOptions>

这是jquery的解析代码:

Here is the jquery parse code:

currentPageData.push({
    title:$(xml).find("page").attr("name"),
    noOfOptions:$(xml).find("noOfOptions").text(), 
    text:$(xml).find("text").text(), 
    instructions:$(xml).find("instructions").text(), 
    option:$(xml).find("option").each(function() {
        $(this).text();
    }),

问题在于选项部分.这仅返回一个对象.我认为这是因为.each函数所致.但是我需要所有它们都存在，并且要返回它们，并且我需要它在这样的for循环中返回文本:

The problem is the option section. This just returns one object. I think this is because of the .each function. But I need all of them, that are present to be returned and i need it to return the text in a for loop like this:

for(i=0;i<noOfOptions;i++) {
    currentPageData[0].option[0];
}

以上操作无效.我该如何解决?

The above is not working. How can I fix it?

谢谢！

推荐答案

要获取选项节点的文本内容，请尝试此操作....

To get the text content of your option nodes try this....

首先，您的xml无效.我添加了一个根节点

Firstly, your xml isn't valid. I've added a root node

var xml = "<root>
               <instructions>Some ins text.</instructions>
               <options>
                   <option>1.png</option>
                   <option>2.png</option>
                   <option>3.png</option>
                   <option>4.png</option>
               </options>
               <noOfOptions>4</noOfOptions>
           </root>",
    xmlDoc = $.parseXML( xml ),
    $xml = $( xmlDoc ),
    $options = $xml.find("option"); // get all option nodes

然后使用jquery.each获取每个选项值

Then to get each option value using jquery .each

$.each($options, function() {
    console.log($(this).text());
});
