使用javascript或jquery在页面底部执行功能

Question

I want to execute the function "nextResults()" if the user has scroll on bottom, using javascript or jquery. My code doesnt work.

My code:

$(window).scroll(function() {
     if($(window).scrollTop() = $(document).height() - $(window).height()) {
          nextResults();
     }
});

Answer 1

改成：

$(window).scrollTop() === $(document).height() - $(window).height()

Answer 2

$(window).scroll(function() {
     if($(window).scrollTop() == $(document).height() - $(window).height()) {
          nextResults();
     }
});

wrong conditional expression, it should be '==' but yours is '='

you can test it here, check the browser developer tools console: JSFiddle
