我是jQuery / JS的新手,我在特定窗口大小中添加或删除功能几乎没有问题。 如果您能查看我的代码并更正它,我将不胜感激。
详细地说,我使用tinyscrollbar插件,我想只出现在特定的窗口大小(让我们说在窗口宽度的650px以上)。
这是我的代码:
<!--****preload latest jQuery and tinyscrollbar plugin, then...****-->
<script type="text/javascript">
function newsScroll() {
$("#newsScroll").tinyscrollbar();
};
/*
if windows width is less than 650px, remove newsScroll function and
switch DIV ID to "spNewsScroll" and vice versa.
*/
function scrollOnOff(width) {
width = parseInt(width);
if (width < 650) {
$(window).unbind(newsScroll);
$("#newsScroll").attr('id','spNewsScroll');
} else {
$(window).bind(newsScroll);
$("#spNewsScroll").attr('id','newsScroll');
}
};
$(function() {
//get window size as of now.
scrollOnOff($(this).width());
$(window).resize(function() {
scrollOnOff($(this).width());
});
});
</script>
