Title: Initialize pqselect with default values selected
Post by: lackofabettername on April 03, 2015, 11:49:04 pm

Hi there,

I am using pqselect in a project where when you load a user it should show the previous selected items when you first created the user. The element is of a multi select type. Also even for single select items, how can we initialize this with the default values or something?

I hope this is clear enough. I'd appreciated any help.

Thanks.

Hi

Setting the default options <option> in select list is simple, just add selected attributes to those options.

But what about when the pqgrid editor options are coming from a JSON array? The following does NOT work: { "value" : theValue, "text" : theText, "selected" : "selected" } or this { "value" : theValue, "text" : theText, "selected" : "true" }.

Or is the only way to handle this to override the column editor Type callback function? e.g. $( ".selector" ).pqGrid( "option", "colModel" )[6].editor.type

To answer my own question, I was able to solve it with the following, but it would be a plus to have it accept a JSON marker:

type: function (ui) {
                    var str = "<select multiple>",
                            options = ui.column.editor.options;
                    if (ui.cellData) {
                        $(options).each(function (i, option) {
                            var selected = '';
                            if (ui.cellData.indexOf(option.value) > -1) {
                                selected = 'selected';
                            }
                            str += "<option value='" + option.value + "' " + selected + " >" + option.text + "</option>";
                        });
                        str += "</select>"
                        ui.$cell.append(str);
                    } else {
                        return 'select';
                    }

                },

The key name is pq_selected.

{ "value" : theValue, "text" : theText, "pq_selected" : true } or this { "value" : theValue, "text" : theText, pq_selected : true }.

Hope it helps.
