Question

我的JSON文件中有以下对象数组，我在解析时遇到问题：

{
    "@name": "zlib License",
    "component": [{
        "name": "iCarousel",
        "url": "http://github.com/nicklockwood/iCarousel/"
    }, {
        "name": "FXKeychain",
        "url": "http://github.com/nicklockwood/FXKeychain/"
    }, {
        "name": "FXForms",
        "url": "http://github.com/nicklockwood/FXForms/"
    }],
    "licensetext": " The zlib/libpng License Copyright (c) &lt;year&gt; &lt;copyright holders&gt; This software is provided 'as-is', without any express or implied warranty. In no event will the authors be held liable for any damages arising from the use of this software. Permission is granted to anyone to use this software for any purpose, including commercial applications, and to alter it  and redistribute it freely, subject to the following restrictions: 1.

Altered source versions must be plainly marked as such, and must not be misrepresented as being the original software. 3. This notice may not be removed or altered from any source distribution."
}

使用这个jquery循环：

function convertJson(data) {
var jsondata = data;
var output = "<ul>";
$.each(jsondata.license, function(k, lic) { 
    $.each(lic.component, function(i, comp) { 
        output += "<li><b>Name: </b>" + comp.name + " <br /> <b>URL</b> : " + "<a href=' " + comp.url + " '>" + comp.url + "</a>" + " <br /> <b>License</b><br /><ul>" + "<div class='license'>" + lic.licensetext + "</div></ul><br />" + "</li>";
    });
});
output += "</ul>";
document.getElementById("licenses").innerHTML = output;
};

convertJson(yourJson);
});

这是我当前的实现，但不确定如何获取内部对象（名称和网址在undefined循环中显示$.each的位置：jsfiddle

Answer 1

更改JSON的结构，以便将单个组件包装在数组中或调整convertJson()

function convertJson(data) {
    //...
    $.each(jsondata.license, function(k, lic) {
        var components = lic.component.length ? lic.component : [lic.component];  // <- this

        $.each(components, function(i, comp) { 
            //...
        });
    });
    //...
};

fiddle

组件元素有一些无效的Json - 一次是单个对象，另一个是对象数组。还有一些代码需要更正。我把它们放在一起：
