JavaScript redirects the page and passes the message using the Post method

There are many ways to redirect pages in JavaScript, and there are many messages that can be delivered, but I only find two ways to pass the Post method.

The first method: use document.write
In the JavaScript function, use document.write ("<input type=" hidden "... >"), output several hidden,name on the page for the parameter name to pass, value for the argument to pass, and finally use " Document.formname.submit "Commit, FormName is the name of the form where hidden is located

The second method: Use hidden in the form
In the display form that you want to submit, such as:
<form name= "MyForm" >
<input type= "text" name= "Text1" size=10>
<%--omitted--%>
<input type= "text" name= "Textn" size=10>
<input type= "hidden" name= "Hidden1" >
<%--omitted--%>
<input type= "hidden" name= "Hidden1" >
<input type= "Submit" value= "OK" >
</form>

It is worth noting that adding the Reset button in the form above does not seem to reset the contents of hidden
