问题 Is it possible to rename a predefined function in JavaScript as we do with php : <?php rename_function('mysql_connect', 'connect' ); ?> 回答1: It's possible in js too. See this function. function rename_function(obj, oldf, newf){ obj[newf]=obj[oldf]; delete obj[oldf]; } Here obj is the closure of the function. Normally if your functions have no closure it's under window object. rename_function(window, 'alert', 'al') 来源： https://stackoverflow.com/questions/10245407/how-to-rename-javascript
