document.write clear all controls of page HI' when the document.write be run, all controls in the web pages will be clear . why? In asp file

Answer 1

Use innerHTML of say a div to write.

<div id="iwanttowritemore"></div>

Then in JS:

document.getElementById("iwanttowritemore").innerHTML = "i can write without clearing the page"

Answer 2

You can't use document.write after the page has loaded, it'll replace the entire page with the contents of said function. Use something else like innerHTML if you need to insert content after the page loads. document.write is kinda frowned upon anyways.
