我对一个简单的代码有疑问
var x = document.getElementsByTagName("th");
var plop = Array.prototype.slice(x);
console.log(x);
console.log(x.length);
console.log(plop);
输出
[item: function, namedItem: function]
0: th.fc-day-header.fc-sun.fc-widget-header.fc-first
1: th.fc-day-header.fc-mon.fc-widget-header
2: th.fc-day-header.fc-tue.fc-widget-header
3: th.fc-day-header.fc-wed.fc-widget-header
4: th.fc-day-header.fc-thu.fc-widget-header
5: th.fc-day-header.fc-fri.fc-widget-header
6: th.fc-day-header.fc-sat.fc-widget-header.fc-last
length: 7__proto__: HTMLCollection
controller.js:309 0
controller.js:310 []
为什么我在这里看到 lenght 7 而 x.length 给出 0 ?
提前致谢
更新:我将代码设置为
$scope.$on('$viewContentLoaded', function(){
}
它现在有效。我还不能设置 onclick 方法,但它正在进步 ^^
