警告：无响应的脚本错误？

Question

嘿，每当我运行我的脚本时，它似乎都会收到此警告消息。

当我在脚本中调用 jquery 函数时会发生这种情况。我已包含下面的脚本并在我调用该函数的位置放置 - 警告：无响应脚本 - 注释。我真的不知道为什么会收到警告消息。

这是我正在开发的项目，如果您想查看它单击此处

我正在尝试更新分页号当选择过滤器选项时。因此，当您选择“黄色”颜色时，您会得到一个结果，即“巨大”，并且应该只显示 1 个页码，而不是 4 个。

如果有人有任何想法可以使其正常工作，那就太棒了。谢谢。

jQuery 脚本：

<script>
$(document).ready(function(){

function paginateIt(){
 //how much items per page to show
 var show_per_page = 3; 
 //getting the amount of elements inside content div
 var number_of_items = $('#content ul').filter(":not(.hidden)").children().size();

 //calculate the number of pages we are going to have
 var number_of_pages = Math.ceil(number_of_items/show_per_page);

 //set the value of our hidden input fields
 $('#current_page').val(0);
 $('#show_per_page').val(show_per_page);

 //now when we got all we need for the navigation let's make it '

 /* 
 what are we going to have in the navigation?
  - link to previous page
  - links to specific pages
  - link to next page
 */

无响应脚本修复

看起来您只是递归调用 paginateIt 。 paginateIt 函数执行大量工作，然后无限地再次调用自身。

要解决此问题，请删除“警告：无响应脚本”评论下方对 paginateIt() 的调用。

这是代码的简化结构，以便您可以更清楚地看到问题：

function paginateIt(){

    // Start filter script
    (function($) {

        $.fn.filterprojects = function(settings) {
            $(this).each(function(i, o){
                /* Binding the filter */
                /* Setup filter selectors */
            });      
        };

        // Warning: Unresponsive Script
        paginateIt();

    })(jQuery); // End filter script

} // End PaginateIt script

paginateIt();

重新分页修复

我会编写这行代码：

//getting the amount of elements inside content div
var number_of_items = $('#content ul').filter(":not(.hidden)").children().size();

如下所示：

var number_of_items = $('#content ul').children().filter(":visible").length;

此外，您还需要在之后调用 paginateIt动画完成后即可正常工作。您可能希望在动画回调中执行此操作，但这里有一个临时解决方法：

/* Triggering the filter */ 
$(o).trigger("filter");
setTimeout(paginateIt, 1500);
