Configuration
The columns in the grid can be used as the basis for a search form to appear above, below, or in place of, the grid. Searching is a way of querying data from the server using specified criteria.
Currently we do not have module for searching on local data i.e when a datatype options is set to local. All the searching is done server side.
There are four approaches:
- a toolbar searching
- a custom searching
- a single field searching
- a more complex approach involving many fields and conditions - advanced searching
These approaches use common options from jqGrid and so can be called only on an already-constructed grid.
Every search method require that some additional module should be included into the package. Also refer to Download or in every specific module on what should be included
All search modules (except cutstom serching and toolbar serching) uses the following definition from language file:
$.jgrid = { ... search : { caption: "Search...", Find: "Find", Reset: "Reset", odata : ['equal', 'not equal', 'less', 'less or equal','greater','greater or equal', 'begins with','does not begin with','is in','is not in','ends with','does not end with','contains','does not contain'], groupOps: [ { op: "AND", text: "all" }, { op: "OR", text: "any" } ], matchText: " match", rulesText: " rules" }, ...
colModel Options
As of 3.5 release jqGrid uses a common search options that can be used on every search method. Below is a list of these options that should be set in colModel. Note that some options are not applicable for particular method.
| Option | Type | Desscription | Default |
|---|---|---|---|
| search | boolean | Determines if the field can be searched. | true |
| stype | string | Determines the search type of the field. Can be text - also a input element with type text is created and select - a select element is created | text |
| searchoptions | object | Object which contain definition, events and other properties for the searched field. See below |
The searchoptions object have the following properties:
The searchoptions are not applicable to custom search method. This method uses separate options.
| Property | Type | Description |
|---|---|---|
| dataUrl | string | This option is valid only for the elements of type select - i.e stype:'select'. The option represent the url from where we load the select element. When this option is set the element will be filled with values from the ajax request. The data should be a valid html select element with the desired options. By example the request should contain <select><option value=“1”>One</option> <option value=“2”>Two</option></select>. This is called only once. |
| dataInit | function | If set this function is called only once when the element is created. To this function we pass the element object. dataInit: function(elem) { do something } Also use this function to attach datepicker, time picker and etc. Example: dataInit : function (elem) { $(elem).datepicker(); } |
| dataEvents | array | List of events to apply to the data element; uses $(“#id”).bind(type, [data], fn) to bind events to data element. Should be described like this: dataEvents: [ { type: 'click', data: { i: 7 }, fn: function(e) { console.log(e.data.i); }}, { type: 'keypress', fn: function(e) { console.log('keypress'); } } ] |
| attr | object | attr is object where we can set valid attributes to the created element. By example: attr : { title: “Some title” } Will set a title of the searched element |
| searchhidden | boolean | By default hidden elemnts in the grid are not searchable . In order to enable searching when the field is hidden set this option to true |
| sopt | array | This option is used only in advanced single field searching and determines the operation that is applied to the element. If not set all the available options will be used. All available option are: ['eq','ne','lt','le','gt','ge','bw','bn','in','ni','ew','en','cn','nc'] The corresponding texts are in language file and mean the following: ['equal','not equal', 'less', 'less or equal','greater','greater or equal', 'begins with','does not begin with','is in','is not in','ends with','does not end with','contains','does not contain'] Note that the elements in sopt array can be mixed in any order. |
| defaultValue | string | If not empty set a default value in the search input element. |
Note: when the dataUrl in searchoptions object is not used for the search type select, the definitions for the select are taken from editoptions value property - i.e editoptions:{value:“1:one;2:two”,…}. See below how to use these options in different search methods.
colModel conventions:
<script> jQuery("#grid_id").jqGrid({ ... colModel: [ ... {name:'price', index:'price', width:60, search:true, stype:'text', searchoptions:{dataInit:datePick, attr:{title:'Select Date'}} }, ... ] ... }); datePick = function(elem) { jQuery(elem).datepicker(); } </script>
What you need to know
- All search modules uses the url parameter in grid to perform the search. In some methods there is additional separate option for the url which can be used too.
- When the search is performed the postData array is filled with the needed data for the search.
- The parameter search in grid options is set to true in order to indicate the searching. Server side the name of this is _search (note the difference) which can be obtained using the GET or POST data array.
For the search we have additional array searchdata array in the grid options. This array extends the postData array.- When the grid is triggered when using the refresh button in Navigator the search option is set to false.
- Every search method creates its own method to clear the searched data from postData array. Use these methods to do this.
Discussion
jQuery('#list').jqGrid('filterToolbar',{stringResult:true, searchOnEnter:false});data from datepicker is inserted into the search box, but the search does not occur until you manually add or remove any character in search field, how to do that would be after the response datepicker an automatic search?
solution
onChange: function(){ jQuery('#list')[0].triggerToolbar(); }HOW TO ^ for solution :)
searchoptions:{dataInit:function(el){$(el).datepicker({ dateFormat:“yy-mm-dd” }).change(function(){$(”#grid_id”)[0].triggerToolbar();});} }
in searchFilter v1.2.9 we haven't searchoptions.value but we have searchoptions.dataValues ! please fix up your document it take me 1 hour !!! :)
in the other hand in search dialog you use dataValues to providing list data and in toolbar search you use value to providing list data !!!!!
“The searchrules will be used only in the searching dialog, but not in the searching filter….” according to the following link by Oleg [http://stackoverflow.com/a/9011733]
i find a bug that the title set is not work: searchoptions :{dataInit:datePick,attr:{title:'Select Date'}}
i debugging the jquery.jqGrid.src.js at the following function and it's worked:
function setAttributes(elm, atr, exl ) {
$.each(atr, function(key, value){
if($.inArray(key, exclude) === -1) { $(elm).attr(key,value); } /** * attr modify by jeffen@bjsunwin at 2012-03-13 */ if(key=='attr'){ $.each(value, function(key, value){ $(elm).attr(key,value); }); } });but what i want to know is that how to get the new file jquery.jqGrid.min.js?
why the parameter “filters” can not be defined as {“groupOp”:“AND”,”rules”:[{“field”:“a.id”,”op”:“eq”,”data”:“2121”,”type”:“integer”}]};
type : date , string , integer , number or customType ….
En los ejemplos, para poder mostrar los valores del campo select te escriben esto:
{name:'tax',index:'tax', width:80, align:“right”, stype:'select', editoptions:{value:”:All;0.00:0.00;12:12.00;20:20.00;40:40.00;60:60.00;120:120.00”}},
y eso no es correcto, porque de esa manera no se muestran. Lo correcto es poner esto: {name:'tax',index:'tax', width:80, align:“right”, stype:'select', searchoptions:{value:”:All;0.00:0.00;12:12.00;20:20.00;40:40.00;60:60.00;120:120.00”}},
When using the toolbar search, how can I make the search CASE INSENSITIVE?
Thank you!
