jQuery Grid Plugin - jqGrid - Topic: default groupField== 'clear' cause grid hangup

waiting on default groupField== 'clear' cause grid hangup

Sorry for false posting-input, I'm sure the source is :

var defGpVal = …..

….

groupField : [ defGpVal ],

The problem is whatever the defGpVal null or blank string , jqGrid will alway post this value as the value of sidx, such as "null desc, id" or " desc, id" (i use 'sortname : 'id','). AND gird do NOT display data return from server when defGpVal is null or blank, so i can not init grid by non-grouping setting when use grouping module (chang to othing setting and then chang back to 'clear' by <select> works good ).

Best regards

Hello,

Not sure if this is a bug. I will test this situation, but rather I will point you to other thing in your code:

You have

var defGpval =

but in grouping you have:

groupingView   : {
      groupField        : [ defGpVal ],
      groupColumnShow : [true],
      groupText        : ['<strong>{0}</strong> ({1})'],
}

Java script is case sensitive.

Regards

Tony

Hi Tony,

I use localStorage to store the last value of grouping-col, and whe init grid read this value

<html>

<select id="chJqgGroup" style="visibility: hidden;">
      <option value="name">name</option>
       <option value="clear">remove</option>
   </select>

<scrip>

var defGpval = …. ;// read last value from cookie or localStorage

groupingView   : {
      groupField        : [ defGpVal ],
      groupColumnShow : [true],
      groupText        : ['<strong>{0}</strong> ({1})'],
}

</scrip>

</html>

when last grouping-select is set to 'clear' after page unload,then next page open the grid will hangup always display 'loading…' or no data display even if server send the correct some data. And by this way,the grid post value contains this:

_search

false

nd

1290516992824

page

1

rows

12

sidx

clear desc, id

sord

asc

I must deal with the incorrect column name of 'clear'.

if i set the default value to null or '' ,also issue. grid post

"sidx

null desc, id

" or

"sidx

desc, id

" // none of first col

It seems to add some condition to deal with NULL/FALSE/blank string or drop 'clear' (if u use striing 'clear' to indicate none-grouping) in grid.grouping.js -> groupingGroupBy()

Best Regards
