Javascript onFocus event with struts

@radzNov 06.2004

Hi all

I am working on a J2EE application with Struts. The jsp that I am working on has four textboxes. What i am supposed to do is that with javascript the moment the focus goes to the second textbox I have to delete the value from the first text box . Similarly with focus on the 3rd text box, i have to delete the value from the 2nd text box and so on.

Please Please help me asap….

Thanks in advance

&lt;input type="text" name="box1" id="box1"&gt;
 &lt;input type="text" name="box2" id="box2" onfocus="document.getElementById('box1').value='';"&gt;
 &lt;input type="text" name="box3" id="box3" onfocus="document.getElementById('box2').value='';"&gt;
 &lt;input type="text" name="box4" id="box4" onfocus="document.getElementById('box3').value='';"&gt;

should do it. If you have to delete all textboxes before the current one

&lt;script type="text/javascript"&gt;
 var boxes=["box1", "box2", "box3", "box4"]; //ids of the text boxes, in order.
 function deleteBefore(box) {
 for(var i=0; i&lt;boxes.length; i++) {
 if(boxes[i]==box.id) break;
 document.getElementById(boxes[i]).value="";
 }
 }
 &lt;/script&gt;
 &lt;input type="text" name="box1" id="box1"&gt;
 &lt;input type="text" name="box2" id="box2" onfocus="deleteBefore(this);"&gt;
 &lt;input type="text" name="box3" id="box3" onfocus="deleteBefore(this);"&gt;
 &lt;input type="text" name="box4" id="box4" onfocus="deleteBefore(this);"&gt;

JSP is server-side as is struts and struts is to do with Apache servers so any struts issues, your in totally the wrong site unless an Apache Guru is viewing...

@HaganeNoKokoroNov 06.2004 — #He's not wrong, he is asking about changing the content of text fields at the client-side using javascript. Just because his server-side is Struts doesn't mean he can't have some client-side code as well, and that is what he asked for. Struts can't change the content of one text field onfocus of another.

It's not a JSP/Struts question, it's a javascript question, and as such belongs in this forum.
