javascript - 在页面加载之前执行 jquery

Question

此代码如何在页面加载之前运行它在页面加载后如何工作

或者有什么方法可以等待这部分代码的其他代码行？

  jQuery("#simulation")
        .on("pageload", ".s-d12245cc-1680-458d-89dd-4f0d7fb22724 .pageload", function(event, data) {
            
    var jEvent, jFirer, cases;
    if(data === undefined) { data = event; }
    jEvent = jimEvent(event);
    jFirer = jEvent.getEventFirer();
    if(jFirer.is("#s-Input_1")) {
      cases = [
        {
          "blocks": [
            {
              "actions": [
                {
                  "action": "jimSetValue",
                  "parameter": {
                    "variable": [ "pid" ],
                    "value":productid
                  },
                  "exectype": "serial",
                  "delay": 0
                }
              ]
            }
          ],
          "exectype": "serial",
          "delay": 0
        }
      ];
      event.data = data;
      jEvent.launchCases(cases);
    }
  });

完整的查找文件代码在那里：

(function(window, undefined) {
  var dictionary = {
    "d12245cc-1680-458d-89dd-4f0d7fb22724": "Screen 1",

  var uriRE = /^(\/#)?(screens|templates|masters|scenarios)\/(.*)(\.html)?/;
  window.lookUpURL = function(fragment) {
      
       if (fragment.indexOf('?') > -1)
{

    var productid=fragment.split("?")[1].split("=")[1];

您可以隐藏整个身体，并在脚本完成后将其显示出来。

CSS：

html { visibility:hidden; }

JS：

$(document).ready(function() {
  //Your code
  document.getElementsByTagName("html")[0].style.visibility = "visible";
});
