Hide the components in Visual JSF 1.x (Woodstock) Using JavaScript
Hi friends, today my friend had a small problem i.e., based on the check-box selected value it shows the text fields (in html <input type="text">),
finally i got the solution for it using the javascript
Here is my solution for the problem.
design the form
1. checkbox group (id = checkboxGroup1 in jsf, id =form1:checkboxGroup1 in html)
2. textfield (id = order in jsf, id = form1:order_field in html)
3. another textfield (id = order2 in jsf, id = form1:order2_field in html)
open the jsp page and add the below script between the head tag( <webuijsf:head"> </webuijsf:head>)
<script>
//<![CDATA[
function ahk(){
var group = document.getElementById("form1:checkboxGroup1").getElementsByTagName('input');
document.getElementById("form1:order_field").style.visibility = "hidden";
document.getElementById("form1:order2_field").style.visibility = "hidden";
var len = group.length;
for(var i =0;i<len;i++){
if("item1" == group[i].value){
if(group[i].checked){
document.getElementById("form1:order_field").style.visibility = "visible";
}
}
if("value" == group[i].value){
if(group[i].checked){
document.getElementById("form1:order2_field").style.visibility = "visible";
}
}
}
}
//]]></script>

Remove the Styles to the textfield component
Before doing this you have to bind the componets, otherwise it won't work.
open the java page and add the below code in _int(), prerender(), methods respectively
_init and prerender methods are pre defined methods you just implement those methods
//in _init method
order.setStyle("position: absolute; left: 336px; top: 96px;visibility:hidden");
order2.setStyle("position: absolute; left: 336px; top: 168px;visibility:hidden");
//in prerender Method
if (checkboxGroup1.getSelected() == null) {
order.setStyle("position: absolute; left: 336px; top: 96px;visibility:hidden");
order2.setStyle("position: absolute; left: 336px; top: 168px;visibility:hidden");
} else {
System.out.println("Entered");
order.setStyle("position: absolute; left: 336px; top: 96px;visibility:hidden");
order2.setStyle("position: absolute; left: 336px; top: 168px;visibility:hidden");
String[] group = (String[]) checkboxGroup1.getSelected();
for (String a : group) {
System.out.println("aa : " + a);
if ("item1".equalsIgnoreCase(a)) {
order.setStyle("position: absolute; left: 336px; top: 96px;visibility:visible");
}
if ("value".equalsIgnoreCase(a)) {
order2.setStyle("position: absolute; left: 336px; top: 168px;visibility:visible");
}
}
}
