View Full Version : How to Hide Textfield in IE and Netscape

Hi All,

I use this code to hide a textfield, it works in IE but it doesn't work when I load the page in Netscape. Any Help?


//To Hide Textbox

document.getElementById("sr").style.display = 'none'

It works in NS 6 or higher... If you try it in an older version of NS, you must use first a browser detector and then, probably, for NS 4.x you may try the syntax


instead of

document GetElementById(id).style

It isn't going to work in Netscape 4.x at all. In NS4 you can only show/hide entire layers, putting the input field into a layer would require adding another set of <form></form> for the field and then more code to pull the result from that field to inset it into a hidden field in the main form. That's a lot of work just to support an obsolete, bug infested browser used by a very small percentage of the web. The best approach for handling NS4 is to treat it just like a version 3 browser and turn off all the "dynamic" sttuff.

It is not so hard to hide/show an element using "id", even in NS 4.x. It is just another syntax. True, you have to use <layer> and <ilayer> tags, as NS 4.x cannot recognize <div> or <span> to be sure that the "id" atribute is accepted, but, after you run a browser detector script, and an objectSetup function, the rest is simple, something like:

function layerSetup(id,visibility) {
if (is.ie5||is.ie55||is.ie6||is.ns6){
this.obj = document.getElementById(id).style;
this.obj.visibility = visibility;
return this.obj;
} else if(is.ie4) {
this.obj = document.all[id].style;
this.obj.visibility = visibility;
return this.obj;
} else if(is.ns4) {
this.obj = document.layers[id];
this.obj.visibility = visibility;
return this.obj;

...now you can make an element visible/hidden for IE4 and NS4 also... If you want to, you may include other style, arguments, such as position, and make thus the object move...

Need anyone the full script?
