我有一列在我的 dojox.data.datagrid 中没有检索到任何数据,但是我放置了一个自定义的可点击标题。我想禁用此列的排序,以便在我尝试单击标题时不会出现三角形。
有什么想法可以实现这一目标吗?
编辑以显示我的代码:
dojo.require("dojox.grid.DataGrid"); //FindTask
dojo.require("dojo.data.ItemFileReadStore"); //FindTask
dojo.require("esri.tasks.find"); //FindTask
var findTask, findParams;
var grid, store;
var searchExtent;
function doFind() {
//Show datagrid onclick of search button and resize the map div.
dojo.style("map", {
"height": "87%"});
esri.show(datagrid);
searchExtent = new esri.geometry.Extent ({
"xmin":-9196258.30121186,"ymin":3361222.57748752,"xmax":-9073959.055955742,"ymax":3442169.390441412,"spatialReference":{"wkid":102100}
});
map.setExtent(searchExtent);
//Set the search text to the value in the box
findParams.searchText = dojo.byId("parcel").value;
grid.showMessage("Loading..."); //Shows the Loading Message until search results are returned.
findTask.execute(findParams,showResults);
}
function showResults(results) {
//This function works with an array of FindResult that the task returns
map.graphics.clear();
var symbol = new esri.symbol.SimpleFillSymbol(esri.symbol.SimpleFillSymbol.STYLE_SOLID, new esri.symbol.SimpleLineSymbol(esri.symbol.SimpleLineSymbol.STYLE_SOLID, new dojo.Color([98,194,204]), 2), new dojo.Color([98,194,204,0.5]));
//create array of attributes
var items = dojo.map(results,function(result){
var graphic = result.feature;
graphic.setSymbol(symbol);
map.graphics.add(graphic);
return result.feature.attributes;
});
//Create data object to be used in store
var data = {
identifier: "Parcel Identification Number", //This field needs to have unique values. USES THE ALIAS!!!
label: "PARCELID", //Name field for display. Not pertinent to a grid but may be used elsewhere.
items: items
};
//Create data store and bind to grid.
store = new dojo.data.ItemFileReadStore({ data:data });
var grid = dijit.byId('grid');
grid.setStore(store);
//Zoom back to the initial map extent
map.setExtent(searchExtent);
}
//Zoom to the parcel when the user clicks a row
function onRowClickHandler(evt){
var clickedTaxLotId = grid.getItem(evt.rowIndex).PARCELID;
var selectedTaxLot;
dojo.forEach(map.graphics.graphics,function(graphic){
if((graphic.attributes) && graphic.attributes.PARCELID === clickedTaxLotId){
selectedTaxLot = graphic;
return;
}
});
var taxLotExtent = selectedTaxLot.geometry.getExtent();
map.setExtent(taxLotExtent);
}
