Javascript,var_dump

web前端-js教程

发现了一个非常好的JavaScript调试方法，目前看到的是可以打印Object/Array/Function/String四种类型，使用方法和PHP中的var_dump()一样，只要直接dump(变量名)即可。

dump(value, [showTypes]) 
@ param value (Any) value to dump 
@ param [showTypes] (Boolean) optional to display each key/value's type 
@ return (Void) returns nothing

The Dump method is based on one of the tags available in Coldfusion ( ) providing the ability to display simple and complex variables in a user friendly way that is perfect for debugging/inspecting data. There is no way to do this with javascript and often I had wanted a method to do this. This method will do just that allowing for an infinite amount of data nesting complete with color coding for different data types, the ability to show/hide the data’s type (String/Number/Boolean/Object/Array/Function), expandable and collapsible tables/keys and cross browser support.
