I am using jqgrid and have simple searching enabled. I am wondering if there is a way to add an additional item in the select list of fields that does not exist as a column
Try adding new hidden column and setting hidedlgand hidden to true, viewable to false.
Documentation link: http://www.trirand.com/jqgridwiki/doku.php?id=wiki:colmodel_options
The suggestion of Bethrezen with the usage of one hidden column is one way which you can use. You should only don't forget to use searchhidden: true
searchoptions.
Another way which I can suggest you can see on the demo:
In the demo I add the
var defaultFilters = {
"groupOp": "AND",
"rules": [
{ "field": "All", "op": "cn", "data": ""}
]
};
...
$('#list').jqGrid('navGrid', '#pager', {add: false, edit: false, del: false},
{}, {}, {},
{
multipleSearch: true,
overlay: 0,
onInitializeSearch: function ($form) {
$form.jqFilter('addFilter', defaultFilters);
},
afterRedraw: function (p) {
if (p.columns.length === $("#list")[0].p.colModel.length) {
p.columns.push({
name: 'All',
label: 'Any Field',
searchoptions: {},
searchrules: {},
searchtype: 'string',
inputtype: 'text'
});
}
//$(this).find('.delete-rule:first').hide();
}
});
In the demo I extended the p.columns
parameter of jqFilter
method with and additional "pseudo column" 'Any Field'. It's just the idea which you can I hope adopt to your exact requirements.
