“window.frames[0].variable” doesn't work in jquery $(function(){})?
문제
In parent.html
I set an iframe with child.html
in it.
in child frame,I write js:
$(function () {
var child = 6;
})
in parent frame,I write js:
$(function () {
alert(window.frames[0].child);
});
but the alert result is "undefined"?
How can I quote another frame's variable correctly with jquery?
해결책
You're seeing undefined
because you're delcaring it as a local variable (scoped only to that document.ready
handler), you would need this in the child frame for a global:
$(function () {
window.child = 6;
});
Also, there's no guarantee that a document.ready
on the parent frame won't execute before the child frame (stick an alert()
in each to see the order)...in fact it should be the opposite. If you're not using it immediately, it's not an issue...if you are you need to execute it later.
