将变量从一个JS文件发送到另一个JS文件

Question

I have ABC.jsp file with the corresponding ABC.js file. I also have XYZ.jsp file with the corresponding XYZ.js file. I have a variable VAR in ABC.js file. I want to send that variable by Post method to the XYZ.js file so that I can use the variable VAR in XYZ.js for some computations . These computations will help me in changing the content of XYZ.jsp file.

I want to send the variable VAR in a javascript function (obviously in ABC.js file) which gets called when a button on ABC.jsp is clicked.

So, can anyone please help me in sending the variable from ABC.js to XYZ.js by post method. And also how to retrieve the variable in XYZ.js file.

I'm novice in this area. Any help will be much helpful for me.

Answer 1

make your ABC.js script with the variable to pass it by GET method to XYZ.jsp page

XYZ.jsp?variable=1234

than, when XYZ.jsp gets rendered with 'variable' parameter passed, it will render this variable somewhere... even as a global JavaScript variable.

// this is going to be rendered in JSP where you just assign the value from the parameter passed to the JSP page

<script>
    myVariable="1234";   // in JPS   myVariable=\"${param.variable}\";
</script>

read myVariable from you ABC.js script
