I want to change between two pages in html with javascript, but when I change with window.location, the code that is after this sentence continues executing.
So when I do, for example, a call to getElementById() it doesn't recognize the element because the page is still loading.
function myFun(){
// ...
window.location = 'page.html';
// ... wait until page.html is loaded
}
How can I wait until the page is loaded to avoid this problem?
When you do
window.location = 'page.html';
you replace the page in the browser, the one containing the code of myFun, by a new page. There is no way for the code following this instruction to be executed.
If you want to execute it, and only after that change page (but I don't see the point), then you might do
document.onload = function(){ window.location = 'page.html'; };
myFun is placed in a separate .js file.
You can use jQuery document.ready or you can create custom bind like this one. In case you use jQuery.
$(document).ready(function() {
window.location = 'page.html';
});
You can't execute code in your own page after doing window.location = 'page.html';. Your page will be replaced by the new page and the code in the current page will no longer be there.
The only ways to execute some code after page.html is loaded into the current window are as follows:
page.html that monitors when it finishes loading and trigger your desired action from there.
