I would like to show a form field textbox only when a certain checkbox is checked, and hide it when it is unhecked. I have gotten the code to make it hide when I check the box, but the textbox is displayed when the page is loaded until I check the box, which is opposite of what I would like to accomplish. I am pretty newbish with javascript so I am sure this is pretty elementary. Thanks for any help.
HTML:
<input type="checkbox" onclick="ShowCCFields(this.value);" name="CAT_Custom_510969" id="CAT_Custom_510969_7" value="Other..." /> Other... <div class="item" id="other"> <label for="CAT_Custom_510972">Other:</label><br /> <textarea onkeydown="if(this.value.length>=4000)this.value=this.value.substring(0,3999);" class="cat_listbox" rows="4" cols="10" id="CAT_Custom_510972" name="CAT_Custom_510972"></textarea> </div> javascript:
// Hide or show textarea if the other checkbox field is checked var voucher = document.getElementById("CAT_Custom_510969_7"); function ShowCCFields(val) { if (!document.getElementById('other')) return; if (val == voucher.checked) document.getElementById('other').style.display = 'inline'; else document.getElementById('other').style.display = 'none'; }
