首先，您的代码结构无效

First, your code has invalid structure

$(document).ready(function() {    
    function space_load() {
        $('#SPACE_TOTAL').load('http://www.klossal.com/portfolio/space.html');
    }    
    space_load(); //Now call the function
});

但是，您可以将其修整

$(function() {
    $('#SPACE_TOTAL').load('http://www.klossal.com/portfolio/space.html');
});

但是，由于您希望在单击元素时执行此操作. 这是您需要的:

But, since you want this on click of an element. This is what you need:

$(function() {
    $("#yourlinkid").click(function() {
        $('#SPACE_TOTAL')
           .html('<img src="preloader.gif" />')
           .load('http://www.klossal.com/portfolio/space.html');
    });
});
