如何重定向到页面然后执行 jQuery 函数调用

Question

How to redirect to page then execute a function with some parameters.

For Example: Page1.js

if (condition is true) {
    window.location.href("Index","Page2");
    someFunction();
}

Is there a way to capture the redirection and execute the function in Page2

Kindly help me, Thanks in advance

Answer 1

Please, try this javascript:

Page 1:

if (true) {
   window.open("page2.html?myVar1=42&myVar2=66", '_blank');
}

Page 2:

var urlParams = new URLSearchParams(window.location.search);

var v1 = urlParams.get('myVar1');
var v2 = urlParams.get('myVar2');

function someFunction(myVar1, myVar2){
  console.log(myVar1);
  console.log(myVar2);
}

someFunction(v1, v2);

Answer 2

Page1 Code :

if (condition is true) {

   window.location.href = '/yourpage2?act=runfunc';

}

Page2 Code:

<script>
var qParam = getUrlParameter('act');

if (qParam=='runfunc') {
someFunction();
}

function getUrlParameter(name) {
    name = name.replace(/[\[]/, '\\[').replace(/[\]]/, '\\]');
    var regex = new RegExp('[\\?&]' + name + '=([^&#]*)');
    var results = regex.exec(location.search);
    return results === null ? '' : decodeURIComponent(results[1].replace(/\+/g, ' '));
};
</script>
