I am using jqgrid advanced search in my project. Everything works fine. Now I have to display a default search condition on click of search button. Please tell me how can I achieve this. I have tried the below code in beforeShowSearch
var postdata =
{
filters: '{"groupOp":"AND","rules":[' +
'{"field":"invdate","op":"gt","data":"2007-09-06"}]}'
};
grid.jqGrid('setGridParam', { search: true, postData: postdata });
It dint work.
If you need to reset searching filters on every opening of advanced searching dialog you can't use beforeShowSearch callback in the case because the postData.filters will be read by searching dialog before calling of beforeShowSearch. What you can do is adding of your custom Searching button with respect of navButtonAdd which looks exactly like the original search button and use search: false option of navGrid to have no standard button. Inside of onClickButton you can reset the filters property of postData before calling of searchGrid.
Alternatively you can reset the value of postData.filters inside of loadComplete callback and use recreateFilter: true option of advanced searching to force creating of new filter on every opening of searching dialog.
The demo demonstrate the last approach. It defines first the variable
var defFilter = '{"groupOp":"AND","rules":[{"field":"invdate","op":"gt","data":"2007-09-06"}]}';
and use loadComplete for resetting the filter
loadComplete: function () {
$(this).jqGrid("getGridParam", "postData").filters = defFilter;
}
I'm using jqGrid 4.2 with the filterToolbar, which works great. I'd like to add some type of custom search to query (server-side) fields that are not part of the colModel.
Prior to 4.0 I would have used filterGrid along the lines of this:
$('#keyword').jqGrid('filterGrid', '#ticket-grid',
{
gridModel: false,
filterModel: [
{ label: 'Keyword', name: 'keyword', stype: 'text'},
{ label: 'Inclued Closed?',name : 'includeClosed', stype: 'checkbox'}
]
});
I understand that this is no longer supported, and an stype: 'checkbox' doesn't work anyway.
How do I do this with the new search module/mechanism?
If I understand you correct you have already on the page, for example above the grid, some controls (text input, selects, chechboxes) which allow the user to define additional criteria of the results which the user want see in the grid. In the case you can use postData with methods (functions) in the way described in the old answer.
If any kind of grid refreshing: request to filter the data from the searching toolbar, changing of the page or the page size, changing of sorting and so on will always follow to the Ajax request to the server. In the case the properties from postData option of jqGrid will be added like other standard parameters (sidx, sord, page, ...). If one from the properties of the postData is defined as function (if a method of postData) then the function will be called to construct the parameter which will be sent to the server. So the current information from you custom searching controls (text input, selects, chechboxes) will be send to the server. In the way you need only use the parameters on the backend to filter the results.
So you have to define fields yourself. For example the text input with id="keyword-input" and checkbos with id="includeClosed" and then use postData in about the following form:
$('#keyword').jqGrid(
// ... other jqGrid options
postData: {
keyword: function () { return $('#keyword-input').val(); },
includeClosed: function () { return $('#includeClosed')is(':checked'); },
}
});
While both autocomplete and select in jqgrid editform place the selected label into the cell, select will place the value (id) in the postdata array where autocomplete will place the label into the postdata array.
is there a way to get the editoption's autocomplete to post the item value (id) instead of the label?
here is the jqgrid code segment i'm using autocomplete in...
$('#tab3-grid').jqGrid({
colNames:['Workorder', 'wo.CUID',.....],
colModel:[
.
.
.
{name:'wo.CUID', index:'cu.LastName', width:120, fixed:true, align:'center', sortable:true, editable:true, edittype:'text',
editoptions:{dataInit:function(el){$(el).autocomplete({ source: 'php/customer-ac-script.php'
, minLength: 1
})
}
},
formoptions:{rowpos: 1, label:'Customer', elmprefix:'* '},
editrules:{required:true}
},
.
.
.
$('#tab3-grid').jqGrid('navGrid', '#tab3-pager',
{view:true, closeOnEscape:true, cloneToTop:true}, // general parameters that apply to all navigation options below.
{jqModal:true, navkeys:[true,38,40], savekey:[true,13]}, // edit options.
{jqModal:true, navkeys:[true,38,40], savekey:[true,13], reloadAfterSubmit:false, afterSubmit: addRecordID}, // add options.
{jqModal:true, afterSubmit: serverMessage}, // del options.
{jqModal:true}, // search options.
{jqModal:true, navkeys:[true,38,40]} // view options.
);
The php code segment:
// construct autocomplete select.
$i = 0;
while($row = mysql_fetch_assoc($result)) {
$output[$i][$crudConfig['id']] = $row['CUID'];
$output[$i][$crudConfig['value']] = $row['LastName'];
logMsg(__LINE__,'I','cu.CUID: '.$row['CUID'].', cu.LastName: '.$row['LastName']);
$i++;
}
// encode to json format and send output back to jqGrid table.
echo json_encode($output);
logMsg(__LINE__,'I','Send json output back to jqGrid table: '.json_encode($output));
Would it be as simple as calling a function under the autocomplete select event or the grid before or after editform submit?
Also, i noticed this note in the jqgrid doc's for datainit: that says...
Note: Some plugins require the position of the element in the DOM and
since this event is raised before inserting the element into the DOM
you can use a setTimeout function to accomplish the desired action.
Would the lack of including the settimeout function be causing the problem?
The server code which provide the JSON response on the autocomplete request has id and value properties. On the other side the standard behavior of jQuery UI Autocomplete is to use label and value properties (see "Datamodel" in the documentation). The value of label property (if any exist) will be used to display in the contextmenu. The value of value property will be placed in the <input> field after the user choose the item from the contextmenu. The value of label property can has HTML markup, but the value of value property must be the text.
So I see the problem as pure problem of the usage of jQuery UI Autocomplete independent on jqGrid. If I understand correct your question you can solve your problem by modification your server side code.
Oleg's answer clarifying the data model for jquery UI's autocomplete, has allowed me to move forward and understand that autocomplete has nothing to do with constructing and sending the postdata array to the server, jqgrid's editform handles it. With that knowledge, i was able to answer my original question and successfully integrate autocomplete into jqgrid. So, in the interest of sharing, i'd like to show you all my motivation and solution.
By default, selecting a label from the autocomplete list put's the value of the selected label/value pair into the text box. All the editform cares about when you submit is what's in the edit fields. So when you submit the editform, the cell's postdata element value will again contain the value of the autocomplete text box. But what if while wanting to post the value of the label/value pair, you want the label of the label/value pair displayed in the text box? You have a problem! How do you get the value of the label/value pair posted to the server?
Well, after spending a few days on it, it turns out to be quite simply. While i'm sure there is more than one solution, here is mine:
add a hidden id column in the grid
define the select: and focus: events in the autocomplete function
in the select: function; insert the selected label into the text box (optional), disable the default behavior of autocomplete, then set the cell of the hidden column to the value of the selected label/value pair
in the focus: function; insert the selected label into the text box(optional), disable the default behavior of autocomplete
add an "onclickSubmit:" event to the navgrid edit options with function name something like "fixpostdata"
in the "fixpostdata" function; get the cell value of the hidden column and insert it into the postdata element associated with the cell.
The following are the grid and javascript code segments i used…
grid segments
{name:'wo_CUID', index:'wo_CUID', width: 70, hidden: true},
{name:'wo.CUID', index:'cu.LastName', width:120, sortable:true, editable:true, edittype:'text',
editoptions:{
dataInit:function(el){ // el contains the id of the edit form input text box.
$(el).autocomplete({
source: 'php/customer-ac-script.php',
minLength: 1,
select: function(event, ui){event.preventDefault();
$(el).val(ui.item.label);
var rowid = $('#tab3-grid').getGridParam('selrow');
// set the hidden wo_CUID cell with selected value of the selected label.
$('#tab3-grid').jqGrid('setCell', rowid,'wo_CUID',ui.item.value);},
focus: function(event, ui) {event.preventDefault();
$(el).val(ui.item.label);}
})
}
},
formoptions:{rowpos: 1, label:'Customer', elmprefix:'* '},
editrules:{required:true}
},
.
.
$('#tab3-grid').jqGrid('navGrid', '#tab3-pager',
{view:true, closeOnEscape:true, cloneToTop:true},
{jqModal:true, navkeys:[false,38,40], onclickSubmit: fixpostdata}, // edit options.
.
.
javascript function
// define handler function for 'onclickSubmit' event.
var fixpostdata = function(params, postdata){
var rowid = $('#tab3-grid').getGridParam('selrow');
var value = $('#tab3-grid').jqGrid('getCell', rowid,'wo_CUID');
postdata['wo.CUID'] = value;
return;
}
The fixpostdata function fires when you submit the editform but befor the postdata array is sent to the server. At this point you replace the cell's postdata element value with whatever you want. In this case, the value of the label/value pair stored in the hidden column cell. When the function returns, the modified postdata array is sent to the server.
Done!
Let´s say I have some sort of datagrid and I want to add a couple chained filters like in this site:
http://www.yelp.com/search?find_desc=bar&ns=1&find_loc=Minneapolis%2C+MN
(sort by,distance,price etc).
Each time a user clciked in a filter link it will update the content of datagrid accordingly. But I would also need to update the links in other filters to take account of the changes. Ex: if i change the order field I need to add/update ?order_field=x in all the other filters links.
What you think is the best way to implement such scenario?
Should i create a function that, when a filter link is clicked, it update the query string params of all the other filters? Or use hidden fields to record the selected option in each filter?
I would like a reusable solution if possible.
Since the data is loading via AJAX, there shouldn't be any links to update - at least not if you mean anchor tags <a>. You don't even need to store the filters in a hidden field.
I would store all the filters as a JSON object. Depending on how your API is set up, you may have to convert the JSON object to something usable by your API or you may even be able to pass on the JSON object directly in the $.ajax request.
This sample code assumes you have a textbox with id="price" in the markup. I intentionally left convert_filters_to_parameters blank because you didnt provide any details as to your API. jQuery will in turn serialize those parameters into a GET or POST request before it sends them out.
var filters = {
distance:null,
price:null,
sortBy:'distance'
}
//this assumes you have a textbox with id="price"
$('#price').changed(function()
{
filters.price = $(this).val();
refresh_data();
});
function refresh_data()
{
var parameters = convert_filters_to_parameters(filters);
$.ajax('/my_api',
{
//i left out a lot of properties here for brevity
data: parameters,
success: function(response) { alert(response); }
});
}
In our application we are using a jqGrid which supports hiding and reordering of columns. When the columns are hidden or reordered we want to store the new settings into our database. But to do this we somehow need to capture the hiding or reordering event. Or possibly to capture when the colModel changes.
Is there any way to capture and handle these events?
Thanks.
You can use 'done' event of the columnChooser. Here is an example:
var grid = $("list");
grid.navButtonAdd(
'#pager',
{caption:"", buttonicon:"ui-icon-calculator", title:"Column choose",
onClickButton: function() {
grid.jqGrid('columnChooser',
{
"done": function(perm) {
if (perm) {
this.jqGrid("remapColumns", perm, true);
}
// here you can do some additional actions
}
});
}
});
UPDATED: If you define sortable option as
sortable: {
update: function (permutation) {
alert("sortable.update");
}
}
and not as sortable:true you will receive the notification about the new order of columns. See the source code of jqGrid for details. The array permutation with integers has the same meaning as in remapColumns functions (see my old answer for details).
You can capture column changes via the sortable parameter as mentinoed in Oleg's "update" above, or as discussed on jqGrid's message board.
However, please note that the array passed to your callback will be relative to the current column order. In other words, saving the array as is after moving multiple columns will not produce the desired results. See my answer on this other stackoverflow question.
