我有一个功能,可以在加载页面时调整图像背景的大小,
$(document).ready(function(){
loadBackground();
});
我想点击按钮时“卸载”或“删除”此加载的函数,以便我可以重新加载此函数,而不是将其加载到页面顶部,
$('.get-image').click(function(){
$(window).unbind("resize",loadBackground);
loadBackground();
return false;
});
但我不能让它发挥作用!有什么想法吗?

根据你的评论,我认为你根本不需要解开:
您首先要在加载页面时加载背景,然后在点击发生时加载背景。
调整图像大小时背景会发生什么应该是绑定到$(window).resize()
的另一个单独的函数...所以整个事情看起来像这样:
($(function() { ... });
与$(document).ready(function() { ... })
相同,只是写得更快:
$(function() {
// Define load BG
function loadBackground() {
/// ...
}
// Define what happens to the BG image on resize
// this doesn't have to change. It should refer
// to the generic `background-image`
$(window).resize(function() {
// ...
});
// load BG when page is ready:
loadBackground();
// load another BG if there's a click:
// This will effectively cancel the previous load bg
$('.get-image').click(function() {
loadBackground();
return false;
});
});
// I'm assuming you're somehow changing which BG image is loaded
// something like loadBackground(image)... and you could initially
// load a default image, and then, if there's a click, you could
// determine what image should be based on what was clicked.
