Infinite loop for check box---> onChange--->text mode---->setValue(-,-,-,-)

[satyanarayana]

Hi All,

I have one field in grid with control type as check box . choices are Apple, Banana , Mango and None(four check boxes).

I wrote code at "text mode" for onChange event.

var fnames={grid.Object}.getValue('G','FRUITNAMES[]',1);

if(fnames=="None"){
{grid.Object}.setValue'G','FRUITNAMES[]',1,['None']);
window.alert("FName is : "+fnames);
}

This code is running infinite times. I want to assign None when user checked None and unchecked the remaining all check boxes if checked.

I have found that using the OnClick event for the check box works much better than using the OnChange event. In example below, I was changing a date field based on whether the box was checked or unchecked. This required that I get the true (checked) or false (unchecked) value of the check box first. My check box field name was DONE. Here is the javascript I used for that. Maybe it will help:

var DONE = {grid.Object}.getValue('G','DONE',{grid.rowNumber});
var doneValue = $u.s.toBool(DONE);
var myDate = new Date();
var curDate=myDate.getMonth()+1+'/'+myDate.getDate()+'/'+myDate.getFullYear();
if(doneValue == true) {
	{grid.Object}.setValue('G','DONE_DATE',{grid.rowNumber},curDate);
} else {
	{grid.Object}.setValue('G','DONE_DATE',{grid.rowNumber},'');
}

Thanks, it is working properly.

And one more issue.
split is not working in that place. why?


splitError.png


var fnames={grid.Object}.getValue('G','FRUITNAMES[]',1);
var fnamesArray=fnames.split(',');//I am getting error at this place.
if(fnames=="None"){
{grid.Object}.setValue'G','FRUITNAMES[]',1,['None']);
window.alert("FName is : "+fnames);
}
else {
for(i=0;i<fnamesArray.length;i++)
window.alert(""+fnamesArray[i]);
}


From the above code ,How can I split the 'fnames' value with comma(,)? And I want to store these values in an array and I want to get that values. Any help . Thanks in advance...

Issue 1:

{grid.object}.setValue('G','FRUITNAMES[]',1,['None'],false);

You need to pass false as the final parameter. This tells setValue "Hey. Don't trigger any events." The onChange event is triggered when you call setValue --- unless you pass in false.

Issue 2:

fnames is probably not a string. What is the typeof fnames? eg:

alert(typeof (fnames));

I did some investigation. getvalue is returning an Object in this form:

['Apple','Banana','Mango','None']

Which is an array. Since it's already an array, you don't need to split it. More Array: https://developer.mozilla.org/en-US/...bjects%2FArray

Thanks to all .. It returns the array type . and I am getting each element from that array by using for loop...

Many Many Thanks to all..!!!

One more help I need!!!!

How can I do different colors for alternate check boxes names?

By using the following statement, I can checked the 'None' value check box. How can I unchecked the 'None' check box when I am checked the atleast one check box in the remain check boxes?
Ex: Apple, Banana, Mango, None.

{grid.object}.setValue('G','FRUITNAMES[]',1,['None'],false);

Unchecking None is probably going to be tricky. You're going to have to track the previous checked state so you can tell if the user clicked 'None' or some other value when you're event is triggered. Otherwise, you'll always end up back in the 'None' selected state - unless, of course, the user deliberately unchecks None before selecting another option.

As for alternating colors for check boxes, that's going to be more involved.

Here's one solution. To implement this in Alpha, you'll need to write custom HTML & CSS for your checkbox control: http://stackoverflow.com/questions/7...box-inside-div

You could probably intercept the generated HTML in the server-side events for the row & insert/modify the displayed HTML.
