Increment the name of variable
提问by user455318
Basically I want to increment the name of the variable. What is the correct syntax to do this?
基本上我想增加变量的名称。执行此操作的正确语法是什么？
for (i=0; i<5; i++) {
eval("var slider_" + i);
var slider_+i = function(){
//some code
}
dojo.addOnLoad(slider_+i);

Why not just use an array?
为什么不直接使用数组？
var slider = [];
for (i=0; i<5; i++) {
slider[i] = function(){
//some code
}
dojo.addOnLoad(slider[i]);
}
Alternatively, you could access them based on the object they are contained within. Assuming they are global variables (hopefully not):
或者，您可以根据它们包含的对象访问它们。假设它们是全局变量（希望不是）：
for (i=0; i<5; i++) {
window["slider_"+i] = function(){
//some code
}
dojo.addOnLoad(window["slider_"+i]);
}
window["something"]is another way to access a global variable named something.
window["something"]是另一种访问名为 的全局变量的方法something。

The right way to do so is to use an object or array. This should work:
正确的方法是使用对象或数组。这应该有效：
var slider = {}; // object
// var slider = [] ; // array
for (i=0; i<5; i++) {
slider[i] = function() {
// some code ...
}
dojo.addOnLoad(slider[i]);
}
