您可以看一下這段代碼，並讓我知道如何將GIS.ZIP文件位於服務器上（../maps/GIS.ZIP）加載到generateFeatureCollection()並且不使用uploadForm？如何在不使用文件輸入的情況下將Zip文件傳遞到函數中
正如你可以看到我現在打電話道場on功能
on(dom.byId("uploadForm"), "change", function (event) {});
上傳和一個zip文件傳遞給generateFeatureCollection()但我想這樣做負載
on(dom.byId("uploadForm"), "change", function (event) {
var fileName = event.target.value.toLowerCase();
if (sniff("ie")) { //filename is full path in IE so extract the file name
var arr = fileName.split("\\");
fileName = arr[arr.length - 1];
}
if (fileName.indexOf(".zip") !== -1) {//is file a zip - if not notify user
generateFeatureCollection(fileName);
}
else {
dom.byId('upload-status').innerHTML = '<p style="color:red">Add shapefile as .zip file</p>';
}
});
function generateFeatureCollection (fileName) {
var name = fileName.split(".");
//Chrome and IE add c:\fakepath to the value - we need to remove it
//See this link for more info: http://davidwalsh.name/fakepath
name = name[0].replace("c:\\fakepath\\", "");
dom.byId('upload-status').innerHTML = '<b>Loading… </b>' + name;
//Define the input params for generate see the rest doc for details
//http://www.arcgis.com/apidocs/rest/index.html?generate.html
var params = {
'name': name,
'targetSR': map.spatialReference,
'maxRecordCount': 1000,
'enforceInputFileSizeLimit': true,
'enforceOutputJsonSizeLimit': true
};
//generalize features for display Here we generalize at 1:40,000 which is approx 10 meters
//This should work well when using web mercator.
var extent = scaleUtils.getExtentForScale(map, 40000);
var resolution = extent.getWidth()/map.width;
params.generalize = true;
params.maxAllowableOffset = resolution;
params.reducePrecision = true;
params.numberOfDigitsAfterDecimal = 0;
var myContent = {
'filetype': 'shapefile',
'publishParameters': JSON.stringify(params),
'f': 'json',
'callback.html': 'textarea'
};
//use the rest generate operation to generate a feature collection from the zipped shapefile
request({
url: portalUrl + '/sharing/rest/content/features/generate',
content: myContent,
form: dom.byId('uploadForm'),
handleAs: 'json',
load: lang.hitch(this, function (response) {
if (response.error) {
errorHandler(response.error);
return;
}
var layerName = response.featureCollection.layers[0].layerDefinition.name;
dom.byId('upload-status').innerHTML = '<b>Loaded: </b>' + layerName;
addShapefileToMap(response.featureCollection);
}),
error: lang.hitch(this, errorHandler)
});
}
