.To whom it may concern,
I have a questions about jqGrid -setGridParam and addRowData
You can check by following the steps below.
Row IDs may be duplicated when following the steps below.
1.
var rows = [{“assignid”:”1000001″,”name”:”taro tanaka”,”id”:”jqg1″}, {“assignid”:”1000002″,”name”:”hana yamada”,”id”:”jqg2″}];
grid.jqGrid(‘setGridParam’, {data : rows}).trigger(“reloadGrid”);
2.
var row2 = {“assignid”:”1000001″,”name”:”taro tanaka”};
grid.addRowData(undefined, row2);
If you check the HTML, there are times when they’ve duplicated.
-Is there a way to prevent duplication with automatic numbering?
-Is it possible to specify the start of row ID numbering?
-If it’s a bug, could you fix it?
I would appreciate your prompt reply.
Hello,
The problem that you have is that your data has ids = jqg1, jqg2 and etc.These id’s are created by default in jqGrid if the user does not specify it.
In Guriddo jqGrid we have two parameters that control this: guid and uidPref. The default values of these are
|
1 2 3 4 |
guid : 1, uidPref: 'jqg', |
You can change it in way you want.
If the addRowData is used and the id is not set a randId function created a id which is equal uidPref + guid and then increases it.
Please note that these id are created at client side per user. Using this way of setting id and add local data and then save it to the server in multi user environment my cause duplicate values.
Now to answer your question
Is there a way to prevent duplication with automatic numbering?
In your case no. You set ids manually that are used from the grid and then use the automatic ids addition without to increase the counter.
Is it possible to specify the start of row ID numbering
Yes it is possible. You can to set the guid parameter to what number you want this way
|
1 2 |
$.jgrid.guid = 10; ... |
See common functions
If it’s a bug, could you fix it?
I do not think that this is a bug, but a way the grid works.
Speaking strongly you can check for duplicates using your own function.
This function can look like this in your situation:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 |
function CheckDupId( grid_id ) { var grid = $("#"+grid_id); // get the existing data id in grid var grid_ids = grid.jqGrid('getDataIDs'); //check to see if the next id is in grid_ids var next_id = $.jgrid.uidPref + ($.jgrid.guid + 1); if( $.inArray(next_id, grid_ids)>-1 ) { alert("Duplicate id"); } else { alert("No duplicate") } } |
Kind Regards
Will
P.S. Sorry for the mistake in function I have fixed it setting the number in brackets ($.jgrid.guid + 1);
