JQuery的的getJSON - 阿贾克斯parseerror [英] JQuery getJSON - ajax parseerror

问题描述

我试图解析与两个JQuery的的getJSON和Ajax以下JSON响应：

I've tried to parse the following json response with both the JQuery getJSON and ajax:

[{"iId":"1","heading":"Management Services","body":"<h1>Program Overview</h1><h1>January 29, 2009</h1>"}]

我也尝试过逃跑的/字符，像这样的：

I've also tried it escaping the "/" characters like this:

[{"iId":"1","heading":"Management Services","body":"<h1>Program Overview <\/h1><h1>January 29, 2009<\/h1>"}]

在我使用的getJSON它剂量不会执行回调。所以，我想它与jQuery阿贾克斯如下：

When I use the getJSON it dose not execute the callback. So, I tried it with JQuery ajax as follows:

$.ajax({
    url: jURL,
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    beforeSend: function(x) {
        if(x && x.overrideMimeType) {
            x.overrideMimeType("application/j-son;charset=UTF-8");
        }
    },
    success: function(data){
        wId = data.iId;
        $("#txtHeading").val(data.heading);
        $("#txtBody").val(data.body);
        $("#add").slideUp("slow");
        $("#edit").slideDown("slow");
    },//success
    error: function (XMLHttpRequest, textStatus, errorThrown) {
        alert("XMLHttpRequest="+XMLHttpRequest.responseText+"\ntextStatus="+textStatus+"\nerrorThrown="+errorThrown);
    }
});

阿贾克斯打错误答警报如下：

The ajax hits the error ans alerts the following:

XMLHttpRequest=[{"iId":"1","heading":"Management Services","body":"<h1>Program Overview </h1><h1>January 29, 2009</h1>"}]

textStatus=parseerror

errorThrown=undefined

然后我尝试了一个简单的JQuery得到调用使用下面的code返回JSON：

Then I tried a simple JQuery get call to return the JSON using the following code:

$.get(jURL,function(data){
    var json = eval("("+data+");");
    wId = json.iId;
    $("#txtHeading").val(json.heading);
    $("#txtBody").val(json.body);
    $("#add").slideUp("slow");
    $("#edit").slideDown("slow");
})

在不用彷徨返回JSON，但EVAL想出了错误无论怎样我已经修改了JSON（Content-Type头，格式等的变化，等等。）

The .get returns the JSON, but the eval comes up with errors no matter how I've modified the JSON (content-type header, other variations of the format, etc.)

我已经拿出的是，似乎有一个问题，在返回的JSON HTML和越来越被解析。不过，我希望，我可能已经错过了一些东西，让我通过JSON得到这个数据。有没有人有什么想法？

What I've come up with is that there seem to be an issue returning the HTML in the JSON and getting it parsed. However, I have hope that I may have missed something that would allow me to get this data via JSON. Does anyone have any ideas?

推荐答案

在JSON字符串你是用它内部的1对象的数组，因此访问你必须先访问数组对象。随着json.php看起来是这样的：

The JSON string you have is an array with 1 object inside of it, so to access the object you have to access the array first. With a json.php that looks like this:

[
    {
        "iId": "1",
        "heading": "Management Services",
        "body": "<h1>Program Overview</h1><h1>January 29, 2009</h1>"
    }
]

我只是想这

$.getJSON("json.php", function(json) {
    alert(json[0].body); // <h1>Program Overview</h1><h1>January 29, 2009</h1>
    alert(json[0].heading); // "Management Services"
    alert(json[0].iId); // "1"
});

我也试过这样的：

I also tried this:

$.get("json.php", function(data){
    json = eval(data);
    alert(json[0].body); // <h1>Program Overview</h1><h1>January 29, 2009</h1>
    alert(json[0].heading); // "Management Services"
    alert(json[0].iId); // "1" 
});

和他们都工作得很好，我。

And they both worked fine for me.
