JSON辅助格式化
平时服务器端开发人员写好后台之后一般写一份简单的接口说明页面，类似：
<form action="test.php" accept-charset="utf-8"> <div><label for="">param_1</label><input type="text" name="param_1" value="value_1"/></div> <div><label for="">param_2</label><input type="text" name="param_2" value="value_2"/></div> <div><label for="">param_3</label><input type="text" name="param_3" value="value_3"/></div> <div><label for="">param_4</label><input type="text" name="param_4" value="value_4"/></div> <div><input type="submit" value="submit"/></div> </form>
由于结果是以json形式返回的，不容易一眼辨认，所以为了方便，对结果进行了简单的处理：
1,由于不能控制返回结果的页面，所以直接对请求进行了拦截并用ajax方式进行重发。
2,格式化返回的json结果，非json结果直接显示。
注：ubuntu下的chromium在处理overflow的问题上貌似有点不一样，所以结果容器写得有点罗嗦。
具体例子：
<!DOCTYPE html> <html> <head> <meta charset="utf-8"/> </head> <body> <div id="page"> <form action="test.php" accept-charset="utf-8"> <div><label for="">param_1</label><input type="text" name="param_1" value="value_1"/></div> <div><label for="">param_2</label><input type="text" name="param_2" value="value_2"/></div> <div><label for="">param_3</label><input type="text" name="param_3" value="value_3"/></div> <div><label for="">param_4</label><input type="text" name="param_4" value="value_4"/></div> <div><input type="submit" value="submit"/></div> </form> </div> <script type="text/javascript" src="../js/jQuery.js"></script> <script type="text/javascript" src="../js/JSONFormat.js"></script> </body> </html>
结果：
JSONFormat.js内容：
