jQuery/Javascript: Defining a global variable within a function?
提问by SnarkyDTheman
I have this code:
我有这个代码:
var one;
$("#ma1").click(function() {
var one = 1;
})
$("body").click(function() {
$('#status').html("This is 'one': "+one);
})
and when I click the body, it says: This is 'one': undefined. How can I define a global variable to be used in another function?
当我单击正文时,它说:这是“一个”:未定义。如何定义要在另一个函数中使用的全局变量?
回答by Rocket Hazmat
Remove the var
from inside the function.
var
从函数内部删除。
$("#ma1").click(function() {
one = 1;
})
回答by keune
If you want to make a global variable bind it to window
object
如果要将全局变量绑定到window
对象
window.one = 1;
回答by Selvakumar Arumugam
var one;//define outside closure
$("#ma1").click(function() {
one = 1; //removed var
})
$("body").click(function(e) {
$('#status').html("This is 'one': "+one);
})
