重定向到特定页面并在js中编写该页面的代码onload

Redirect to specific page and write code onload of that page in js

在重定向到其他页面时,应该执行一些代码,但这是不可能的

if (something === true) {
  /* Redirect to someotherpage.php */  
  window.location.href = "someotherpage.php"  
  var test = "someotherpage.php";  

  /* onload of someotherpage.php, execute this introjs step */  
  $(test).load(function() {  
    if (window.location.href === test) {  
      /* unable to execute this */  
      introJs().addStep({  
        element: $('#ck-dashboard-pending-task')[0],  
        intro: 'Here you can see the todo list',  
        position: 'left'  
      }).setOption('scrollToElement', true).start();  
    }  
  });  
}  

您的问题是您试图在加载另一个页面时在页面内执行代码。你不能这样做(你可以在单页应用程序中这样做,但那是另一回事了)。

在您的 someotherpage.php 中,您应该添加以下代码:

$(window).load(function(){  
      introJs().addStep({  
      element:$('#ck-dashboard-pending-task')[0],  
      intro:'Here you can see the todo list',  
      position:'left'  
      }).setOption('scrollToElement', true).start();
  });  

并且您应该删除页面中的这部分代码: var 测试 = "someotherpage.php";

/* onload of someotherpage.php, execute this introjs step */  
  $(test).load(function() {  
    if (window.location.href === test) {  
      /* unable to execute this */  
      introJs().addStep({  
        element: $('#ck-dashboard-pending-task')[0],  
        intro: 'Here you can see the todo list',  
        position: 'left'  
      }).setOption('scrollToElement', true).start();  
    }  
  }); 

编辑: 正如 OP 所要求的,这里有一个澄清: 在您的第一页中,您可以这样做:

if (something === true) {
  /* Redirect to someotherpage.php */  
  window.location.href = "someotherpage.php?some_condition_you_want_to_check=1"
}  

someotherpage.php:

$(window).load(function(){  
    $.urlParam = function(name){
        var results = new RegExp('[\?&]' + name + '=([^&#]*)').exec(window.location.href);
        if (results==null){
           return null;
        }
        else{
           return results[1] || 0;
        }
    }

    if($.urlParam('some_condition_you_want_to_check') !== null){
        introJs().addStep({  
            element:$('#ck-dashboard-pending-task')[0],  
            intro:'Here you can see the todo list',  
            position:'left'  
            }).setOption('scrollToElement', true).start();
        });  
    }
  }

当然,我的代码是未经测试且肯定有待改进的部分,但这应该让您了解需要做什么才能实现您的目标。
