Question

我正在尝试使用Disqus api，我需要运行一些修改Disqus评论主题的javascript代码。

如何在加载Disqus线程后运行javascript代码？

Answer 1

我遇到了类似的问题。我能想出的唯一可行解决方案是运行setInterval()来检查Disqus容器div的高度。

示例：

var editable = true; // set a flag
setInterval(function() {
// Initially Disqus renders this div with the height of 0px prior to the comments being loaded. So run a check to see if the comments have been loaded yet.
  var disqusHeight = $('#dsq-2').height();
  if ( disqusHeight > 0 ) {
    if (editable) { // To make sure that the changes you want to make only happen once check to see if the flag has been changed, if not run the changes and update the flag.
      editable = false;
      // Your code here...
    }
  }
}, 100);

以下是Brandon Morse的修改代码，用于新版本Disqus和脚本在Disqus加载评论时停止。

var interval = setInterval(function() {
    var $ = jQuery;
    var disqusHeight = $('#disqus_thread').height();
    if ( disqusHeight > 52 ) {  // height 52px is header of Disqus, more than 52px means that disqus load comments
      // Your code
        clearInterval(interval); // after loaded comment we stop this script
    }
}, 100);

使用flag来避免循环：

evento.add(window, "load", function () {
    var w = window,
    d = document,
    a = d.getElementById("disqus_thread") || "",
    disqus_shortname = a ? (a.dataset.shortname || "") : "",
    embed_js_src = ("https:" == w.location.protocol ? "https" : "http") + "://" + disqus_shortname + ".disqus.com/embed.js",
    g = ".grid",
    h = ".grid-item",
    k = ".grid-sizer",
    grid = d.querySelector(g) || "";
    function build_layout() {
        if (grid) {
            if (w.Packery) {
                var pckry = new Packery(grid, {
                        itemSelector : h,
                        gutter : 0
                    });
            } else if (w.Masonry) {
                var msnry = new Masonry(grid, {
                        itemSelector : h,
                        columnWidth : k
                    });
            }
        }
    }
    build_layout();
    if (a && disqus_shortname) {
        w.loadJS && loadJS(embed_js_src, function () {
            if (grid) {
                var f = !1;
                setInterval(function () {
                    var disqus_thread_height = a.clientHeight || a.offsetHeight || "";
                    if (108 < disqus_thread_height && !1 === f) {
                        /* alert(disqus_thread_height); */
                        build_layout();
                        f = !0;
                    }
                }, 100);
            }
        });
    }
});

试试这个：

function disqus_config() {
  this.callbacks.onReady.push(function () {
    // your code
  });
}

Answer 5

  `<script> 
        var disqus_config = function () {
         this.callbacks.onReady = [function(data) {
            //your code here
          }];
         this.callbacks.afterRender= [function(data) {
            //your code here
          }];
         this.callbacks.beforeComment= [function(data) {
            //your code here
          }];
         this.callbacks.onInit= [function(data) {
            //your code here
          }];
         this.callbacks.onNewComment= [function(data) {
            //your code here
          }];
         this.callbacks.onPaginate= [function(data) {
            //your code here
          }];
         this.callbacks.preData= [function(data) {
            //your code here
          }];
         this.callbacks.preInit= [function(data) {
            //your code here
          }];
         this.callbacks.preReset= [function(data) {
            //your code here
          }];

        };
  </script>`
