Question

Using Javascript to show / hide rows SharePoint Newform.aspx

Asked by: SPNewBee

I am at my wits end trying to figure out a solution.
Using the JavaScript below i was able to "hide" a text field called Text 1.  Needing to hide/show the Text 1 row based upon a select drop down value, but unable to find a way to "stuff" the drop down element with an onselect.  

The flow:
User opens a newform.aspx in a sharepoint list
Text 1 value is hidden using the code below
User selects "Some Specific Value" in a drop down choice field and Text 1 rows un-hides.
User selects "Some other value not testing for" in the drop down and the Text 1 row hides.



Any help would greatly be appreciated.

_spBodyOnLoadFunctionNames.push("hideFields");
function hideFields() 
{
var control = findacontrol("Text 1");
control.parentNode.parentNode.style.display="none";
}
 function findacontrol(FieldName) {
var arr = document.getElementsByTagName("!");
for (var i=0;i < arr.length; i++ )
{
if (arr[i].innerHTML.indexOf(FieldName) > 0)
{         return arr[i];      }
}
}
-------------------------------------------------------------------
 
 
//This is the pure html version of what is needed:
 
 
function testCustom(selObj)
{
if(selObj.options[selObj.selectedIndex].value == 'Not in this List')
{
//Show the textbox
document.yourtextboxname.style.visibility = 'visible';
document.yourtextboxname.style.display = '';
}
else
{
//Hide the textbox
document.yourtextboxname.style.visibility = 'hidden';
document.yourtextboxname.style.display = 'none';
 
}
}

raybies- The hideMaBit function is not working. Is the [if(window.event.srcElement.value=="Some Specific Value"] correct or just for illustration purposes ?  

 

by: SPNewBeePosted on 2009-09-08 at 18:14:53ID: 25287551

should it be window.event ?

Correction: Your function "findacontrol" is not working.

_spBodyOnLoadFunctionNames.push("hideFields");
var myDropDown, control, myRow;
function hideFields(){
        try{
                myDropDown = findMaBiach("DropDown","select");
                alert(myDropDown.value);
                myDropDown.attachEvent("onchange", hideMaBit);          
                control = findacontrol("Text 1");
                myRow = control.parentNode.parentNode;
                myRow.style.display="none";     
        }
        catch(e){}
}
 
function findacontrol(FieldName) {
        var arr = document.getElementsByTagName("!");
        for (var i=0;i < arr.length; i++ ){
                if (arr[i].innerHTML.indexOf(FieldName) > 0){ 
                alert(arr[i].id) 
                        return arr[i];                             
                }
        }
}
 
function hideMaBit(){
        if(window.event.srcElement.value=="Some Specific Value"){myRow.style.display = "block";}
        else{myRow.style.display = "none";}
}
 
function findMaBiach(title,type){
	var Biach = document.getElementsByTagName(type);
	for(i=0; i<Biach.length;i++){
		if(Biach[i].title.indexOf(title)>-1){
			return Biach[i];
		}
	}
}
