为什么未定义此功能? [英] Why is this function undefined?

问题描述

我希望我已经过去了...但是为什么在单击按钮时未确定调整大小?

I was hoping i was past this... but why is is resize undefined on Button click?

    $(document).ready(function(){
    var w = [320, 480];
    var h = [480, 620];

    function resize (input){
        $("scale").width(w[input]);
        $("scale").height(h[input]);
    }

    $.each(w, function(i, val){
        $("<button onclick='resize("+i+")'>"+val+"</button>").appendTo("body");
    }); 
});

推荐答案

因为它位于document.ready函数中.

Because its inside the document.ready function.

您需要在全局级别具有resize功能，DOM才能看到它.

You need to have the resize function at the global level for the DOM to see it.

但是，更好的方法是使用jQuery的"on"功能.

However a better way of doing it would be to use the jQuery "on" function.
