Hello,
I am trying to wire up some print functionality on an app that I am building.
I basically just copied the code from the JSAPI samples page ... just to get a sense of how it works,
When I click on the "Print" button, it heads off like the samples do, but I get the following error:
js.arcgis.com/3.12/esri/tasks/Geoprocessor.js?1424148233374:14 Uncaught TypeError: Cannot read property 'query' of undefined
I am not sure how to resolve this, it is the first time I have used the 10.2 print task.
I have also tried to publish my own templates as a print task and that is getting the same error.
Could someone point me in the right direction on this?
thx
David
Code is below:
doPrint: function() {
console.log("In the startup for print!");
//esriConfig.defaults.io.alwaysUseProxy = false;
//esriConfig.defaults.io.proxyUrl = "";
// get print templates from the export web map task
var printInfo = esriRequest({
"url": this.printUrl,
"content": { "f": "json" }
});
printInfo.then(this.handlePrintInfo, this.handleError);
},
handlePrintInfo: function (resp) {
var layoutTemplate, templateNames, mapOnlyIndex, templates;
layoutTemplate = arrayUtils.filter(resp.parameters, function (param, idx) {
return param.name === "Layout_Template";
});
if (layoutTemplate.length === 0) {
console.log("print service parameters name for templates must be \"Layout_Template\"");
return;
}
templateNames = layoutTemplate[0].choiceList;
// remove the MAP_ONLY template then add it to the end of the list of templates
mapOnlyIndex = arrayUtils.indexOf(templateNames, "MAP_ONLY");
if (mapOnlyIndex > -1) {
var mapOnly = templateNames.splice(mapOnlyIndex, mapOnlyIndex + 1)[0];
templateNames.push(mapOnly);
}
// create a print template for each choice
templates = arrayUtils.map(templateNames, function (ch) {
var plate = new PrintTemplate();
plate.layout = plate.label = ch;
plate.preserveScale = true;
plate.format = "PDF";
plate.layoutOptions = {
"authorText": "Made by: Esri's JS API Team",
"copyrightText": "<copyright info here>",
"legendLayers": [],
"titleText": "Pool Permits",
"scalebarUnit": "Miles"
};
return plate;
});
// create the print dijit
var printer = new Print({
"map": global.MAP, // ---> yes, I know <sigh!>
"templates": templates,
url: this.printUrl
}, dom.byId("print_button"));
try {
printer.startup();
}
catch (ex) {
console.log(ex.message);
}
printer.on('print-start', function () {
console.log('The print operation has started');
});
printer.on('print-complete', function (evt) {
console.log('The url to the print image is : ' + evt.result.url);
});
},
