Javascript function call in url

Question

I want to login a website with javascript and i dont know it is allowed. I use javascript code in url and it gives me Invalid left-hand side in assignment at :1:10 error.

javascript:document.getElementById("OtherUsername")="myid";document.getElementById("OtherPassword")="mypassword";$("#btnSend").click();

you need to use value attribute document.getElementById("OtherUsername").value = "myuid", not sure what you are trying to do but you aremixing jquery n JS — Vinod Louis

As Vinod stated, you are trying to assign myid (a string) to document.getElementById("OtherUsername"), an object. That won't work. You need to assign it to document.getElementById("OtherUsername").value

This should work:

javascript:document.getElementById("OtherUsername").value="myid";document.getElementById("OtherPassword").value="mypassword";$("#btnSend").click();

The last bit $("#btnSend").click(); will only work if they have jQuery active on that site, or if you include it through use of a plugin somehow.

you can not Assign a value to a dom element

if OtherUsername element and OtherPassword element is a form you can follow my code

document.getElementById("OtherUsername").value="myid";
document.getElementById("OtherPassword").value="mypassword";
$("#btnSend").submit(); //btnSend should be the from id
