问题
I'm using jqGrid formatter action with a long grid, I'm trying to position the delete dialog in the center of the screen, I did that already but for some reason the window scrolls to the top of the grid and the dialog becomes invisible to the user
Click here for a screencast of the issue
Here's the code used:
// define handler function for 'afterSubmit' event.
var actionStatus = function(response,postdata){
//alert($.parseJSON(response.responseText).USERDATA.MSG);
aData = $.parseJSON(response.responseText).USERDATA;
if (aData.STATUS){
$.jgrid.info_dialog("Success", aData.MSG, $.jgrid.edit.bClose,{buttonalign:'right'});
var thisId = aData.ID;
$("#list").jqGrid('setGridParam',{loadComplete: function(){$(this).jqGrid('setRowData', thisId, false, 'mybold'); $("#" + thisId).effect("highlight", {color:"orange" }, 3000);}});
}
else {
$(".topinfo").html(aData.MSG);
}
return [aData.STATUS, aData.MSG, aData.ID];
}
$(document).ready(function(){
var grid = $("#list");
var lastSel;
var selICol; //iCol of selected cell
var selIRow; //iRow of selected cell
$("#list").jqGrid({
url:'data.cfc?method=GetRecords', //CFC that will return the users
datatype: 'json', //We specify that the datatype we will be using will be JSON
//The JSON reader. This defines what the JSON data returned from the CFC should look like

回答1:
You don't posted the code of center method which you use or describe which plugin you use. In any way I think that you should use delDiv.center(); inside of afterShowForm and not inside of beforeShowForm.
Like you can see on the demo the problem with scrolling should not exist in general.
