Js clicks the button to jump to another new page

Click the button how to jump to another page? We may need it in website production, because sometimes we need to do this, especially when we make a button into a picture, and click on the picture to go to a new page, how do we do it?

This effect can be achieved by: onclick="window.location=' new page '".

1. Jump directly from the original form

The following code

Window.location.href =" the page you want to go to ";

2. Open the page in the new form with:

The following code

Window.open (' the page you want to go to ');

Window. The history. The back (1); Go back to the previous page

The following code

< Input type="submit" name=" submit" value=" agree "onclick=window.open(//www.jb51.net/)>

What do I do if I want to verify that the input is filled in when I click the button to submit? When the user name input or other is empty, click the button not to submit, you can do as follows.

The following code

<input type="submit" name="submit" onclick="open()">
<script language=javascript>

fuction open(){
if(!document.form_name.username.value) {
alert(" Please enter user name! "); document.form_name.username.focus(); return false;
}else document.form_name.action="aaa.htm";
}

</script>

So, when the value is empty, clicking the button still won't jump to another page? That's it.
