Remove first character with jQuery
提问by sephiith
How would I go about removing the first character from this.className in the below line? The first variable will be _ and then a number. I just want the number to be assigned to className.
我将如何从下一行中的 this.className 中删除第一个字符？第一个变量将是 _，然后是一个数字。我只想将数字分配给 className。
className = this.className;
Furthermore I am changing "$('.inter').html(window[link[className]]);"to use an array instead of the className variable. Is the below code the correct way to use an array with the index as a variable?
此外，我正在更改"$('.inter').html(window[link[className]]);"使用数组而不是 className 变量。下面的代码是使用索引作为变量的数组的正确方法吗？
$('.inter').html(window[link[className]]);

No need to use jQuery for that, just plain ol' javascript using .substring
无需为此使用 jQuery，只需使用简单的 ol' javascript .substring
var trimmed = this.className.substring(1);
