I have disabled=true
textboxes and combox boxes in my jsp.
When I try to map those value back to action, they disappear.
I don't want to call to DB again.
How can I set those disabled=true
textboxes
and combo boxes
's data value into hidden values
?
Thanks ahead.
The property of disabled elements' value not being submitted with the form is not an issue with struts2, but an HTML behavior. To handle this behavior, use the following implementations:
See the following implementation for select element. You may make use of the id attribute of s:select to set the html id of select element.
<select id="demoSelect" class="readonly">
<option value="0">A</option>
<option value="1">B</option>
<option value="2" selected="selected">C</option>
<option value="3">D</option>
<option value="4">E</option>
<option value="5">F</option>
</select>
<input type="hidden" value="2" name="demoSelectDefault"/>
jQuery:
$(document).ready(
function() {
$("select.readonly").live('change', function() { //live() makes sure that this is executed if you apply the class to the element even after the initial load. So, if you set the readonly class to a select element, you are done.
var selectElement = this;
$("input[type=hidden][name=" + this.id + "Default]").each( //This is implemented in case of multiple select support. You will need to select nothing at first and then make this select each of this element
function() {
selectElement.value = this.value;
}
);
});
}
);
Here, when you implement this using struts, populate the s:select, then use an s:hidden element to generate a corresponding default value.
