javascript - Uncaught RangeError: Maximum call stack size exceeded-PHP中文网问答

最近在调试app与js的交互，没接触过js，总是各种的问题，自己写的测试东西，报了题目这个错误。

<script type="text/javascript">
    window.changeValue = function (paramObj) {
        for (var i in paramObj) {
            if (!(paramObj[i] instanceof Function)) {
                if (paramObj[i] === "nil") {
                    delete paramObj[i];
                } else if (paramObj[i] === "false" || paramObj[i] === "False" || paramObj[i] === "FALSE") {
                    paramObj[i] = false;
                } else if (paramObj[i] === "true" || paramObj[i] === "Ture" || paramObj[i] === "TRUE") {
                    paramObj[i] = true;
                }

            }
        }
        return paramObj;
    };

    window.uploadPic = function () {
        var funcParam = {

            info: { prod: $("#pd").val() },
            type: $("#type").val(),
            size: {
                width: $("#picWidth").val(),
                height: $("#picHeight").val()
            },

            success: function (rspData) {
            },
            error: function (errCode, msg) {
            },
            cancel: function () {
            }
        };
        //alert('你好');
        //alert();
        uploadPic(changeValue(funcParam));
    };

    </script>

<body>
    <td><input style="width:90%" type="text" value="hei" id="pd"></td>
    <td><input style="width:90%" type="text" value="0" id="type"></td>
    <td><input style="width:90%" type="text" value="400" id="picWidth"></td>
    <td><input style="width:90%" type="text" value="400" id="picHeight"></td>
    <input style="width:90%" type="button" onclick="uploadPic()" value="上传图片">
</body>

点击上传图片以后就会报这个错误。
