问题描述
在jQuery中,是否可以将变量作为常量?我知道在许多其他语言中是不可能的,但是jQuery从未使我感到惊讶.无论如何,也许这不是正确的问题,我正在尝试使用循环索引作为ID,其中ID调用方法.通过每个循环,ID都会发生变化,而我试图从一组不同的 a
元素中触发相同的功能.如何更改代码以具有动态调用方?
In jQuery, is it possible to have a variable as a constant? I know it is not possible in many other languages, but jQuery never ceases to surprise me. Maybe this isn't the right question, anyway, I am trying to use a loop index as an ID, of which the ID calls a method. Through each loop the ID changes and I'm trying to trigger the same function from a set of different a
elements. How can I change my code to have a dynamic caller?
for(var i in data.items) {
var id = $(i);
var viewMore = $("<a href=# id=" + id + ">View More</a>");
id.on('click', function(x) {
// do something
}
}
推荐答案
jQuery 是javascript库,它不是语言,并且没有常量.您只能创建一个虚数常量,该常量与变量不同.
jQuery is javascript library, It is not language, and it doesn't have constants.You can only create an imaginary constant, which will differ from variables.
例如:
var MY_CONSTANT = "my constant value";
对于你的便条,对我而言,更正确的方法是:
As for your sript, as for me, the more correct way is:
// It is your constant
var VIEW_MORE = $("<a href='#'>View More</a>");
for(var i in data.items)
{
VIEW_MORE.clone().attr('id', i).on('click', function(x)
{
// do something
}
}
