how would i use document.write to write this input box? i can do it without
quotes but i need them for my purpose

<input type="textbox" name="input" value="something">

i did this but it doesn't have the double quotes
document.write( '<input type="textbox" name="input" ' + 'value="' +
entereddata+ '">');

2.
filter(enetereddate);
how can i filter out single quotes double quotes and other character that
might cause problem from a string? this string will be added to the value
param of the textbox.

this will cause problem, say i enetered this in a textbox

sjdkfjdfkd "dfdfd" dfdfd

when i do document.write and write this to the value parameter of the new
textbox it will be like this

<input type=textbox name=input value=sjdkfjdfkd "dfdfd" dfdfd>

i would like a function that can replace the quotes in the input string to
&quot;
and also any other harmful characters


Thanks in advance,
Aaron
 
Hi,

First off, these are not the most appropriate groups for your question, but
anyway - see inline:

You need to escape the quotes:

document.write( "<input type=\"textbox\" name=\"input\" value=\"" +
entereddata+ "\">");

If you use only double quotes you will need to escape only the double quotes
(it's easier). There is no ready function in jscript for this, but you can
use the replace function:

var v = "some \"NEW\" test";
var quot = new RegExp("\"", "g");
document.write("<input type=\"text\" id=\"input\" value=\"" +
v.replace(quot, "&quot;") + "\"><br/>");

Hope this helps
