I have a function which is called when a file is needed to be read in a folder. In this case since i have 3 files in that folder, it is called 3 times consecutively. I need to save all files info into array mapped_data2 like that:
mapped_data2[0] = inner_data1 //first file info,
mapped_data2[1] = inner_data2 //second file info etc.
However using my code i am having just the first files information 3 times. I am a bit confused with global variables, if you can point out the problem, i would appreciate it.
here is the code:
var mapped_data = [];
var mapped_data2 = [];
function o(msg) {
if (msg.data) {
var inner_data = [];
var lines = msg.data.split('\n'); //read lines of a file
for (var i = 2; i < lines.length; i++) {
if (lines[i].length > 0) {
.. //do same data format here
inner_data.push([son, vactual, voutput]);
}
}
mapped_data = inner_data;
}
else {
if (msg.topic == "/somefolder/somefolder") {
for (var i = 0; i < msg.args.length; i++) {
var filename = msg.args[i];
aw.get(filename);
}
}
}
}
function de() { //where i wanted to use these files info
for (var i = 0; i < 3; i++) {
mapped_data2[i] = { key: "Group" + (i + 1), values: mapped_data };
}
var datam = mapped_data2;
var den = JSON.stringify(datam);
document.write(den);
};
function init() {
..//create new client called aw for the server application and start it;
..//if the connection is established:
aw.onmessage = o;
aw.get("/somefolder/somefolder"); // request list of files in a folder
};
//when html page is being onload, call the functions init() and de()
var mapped_data2 = [];
function o(msg) {
var mapped_data = []; // this doesn't need to be global
if (msg.data) {
var inner_data = [];
...
mapped_data = inner_data;
} else {
...
}
mapped_data2.push({ key: "Group" + mapped_data2.length + 1, values: mapped_data };)
// do more stuff as in den()
}

I'm using pdfjs to display a PDF form (acroforms example). If I fill in some fields, how do I get those annotations.
I've tried:
pdfPage.getAnnotations().then(function(a) {
for(var i = 0;i < a.length; i++) {
console.log(a[i].id + ' - ' + a[i].fieldValue);
}
});
But all I get are empty fieldValues. I guess I'm getting them from the original PDF. How do I access the live document which includes the new annotations?
async getAnnotations() {
var result = {};
var pages = PDFViewerApplication.pdfDocument.numPages;
for (var i = 1; i <= pages; i++) {
var page = await PDFViewerApplication.pdfDocument.getPage(i);
var annotations = await page.getAnnotations();
for (var j = 0; j < annotations.length; j++) {
var element = annotations[j];
// Field Name
if (result[element.fieldName] == null) {
result[element.fieldName] = null;
}
var val = PDFViewerApplication.pdfDocument.annotationStorage.getOrCreateValue(element.id);
if (element.radioButton) {
if (val.value) {
result[element.fieldName] = element.buttonValue;
}
} else if (element.checkBox) {
result[element.fieldName] = val.value ? "On" : "Off";
} else {
result[element.fieldName] = val.value;
}
}
};
return result;
}
You should save values written by user in a local variable
Then you should create a xfdf file ( xml file by Adobe ) , look for Example nere : https://developer.salesforce.com/page/Adobe_XFDF . The xfdf should then be merged with original pdf to produce a new compiled pdf
I am making 3 get JSON calls in myFunction() that gets called on a button click. 2 of these getJSONs depend on each other for their execution. It basically parses through 10 web pages and collects some data. With this data it will go to another page and collect some other data. I want to display "DONE" at the end of myFunction so the user knows that we have finally got all data and the search operation is complete. However these calls, I think, are asynchronous, so I use deferred objects. But even though I pass all calls to $.when.apply(call1,call2,call3), it displays the "DONE" before any data is printed on the console. Once it prints "DONE", then it starts to print the results. How can I modify my code so that I would be able to display "DONE" only when myFunction has ran completely for all 10 pages and has printed all data on the console.
var call1 = [];
var call2 = [];
var call3 = [];
function myFunction() {
data3 = [];
url = ''; // some URL here
call3.push($.getJSON(url, function(data4) {
data3 = data4;
}));
for (var page = 1; page < 10; page++) {
(function(page) {
url = 'http://example.com/' + page;
call1.push($.getJSON(url, function(data1) {
for (var num = 0; num < data1.standings.results.length; num++) {
(function(num) {
url = 'http://example.com/' + data1.entry[num];
call2.push($.getJSON(url, function(data2) {
for (var i = 0; i < 15; i++) {
(function(i) {
console.log(data3.ele[(data2.p[i].element) - 1].x);
return;
}
})(i);
}
})
);
})(num);
}
})
);
})(page);
};
$.when.apply(call1, call2, call3).then(function() {
console.log("DONE");
});
}
I was finally able to solve this problem. As mentioned in the comments, we need to chain various promises and the function structure should match the structure of the when command. So, in the function as call1 was pushed first, I need to call the when command for call1 and then nest the subsequent commands and so on.
var call1 = [];
var call2 = [];
var call3 = [];
function myFunction() {
data3 = [];
url = ''; // some URL here
call3.push($.getJSON(url, function(data4) {
data3 = data4;
}));
for (var page = 1; page < 10; page++) {
(function(page) {
url = 'http://example.com/' + page;
call1.push($.getJSON(url, function(data1) {
for (var num = 0; num < data1.standings.results.length; num++) {
(function(num) {
url = 'http://example.com/' + data1.entry[num];
call2.push($.getJSON(url, function(data2) {
for (var i = 0; i < 15; i++) {
(function(i) {
console.log(data3.ele[(data2.p[i].element) - 1].x);
return;
}
})(i);
}
})
);
})(num);
}
})
);
})(page);
};
$.when.apply($, call1).then(function(){
$.when.apply($, call2).then(function(){
document.getElementsByName('output')[0].value+="Search Completed"+'\r\n';
});
});
}
The following is the full JavaScript code for a quiz. It works perfectly on desktop browsers. However, when I went to test it on my phone, it doesn't work.
Mobile loads the JSON quiz, but after all the answers are selected, it does not freeze all the selected answers and display the results. Instead, nothing happens, no result is shown/calculated, and the user can continue to select answers.
I'm not experienced with JavaScript on Mobile and don't know what is causing the problem.
I've deleted a few parts of the code that simply appended html in order to cut down on size.

If you ever try to see console log on a mobile device, you might notice that there is a JavaScript error because iOS Safari is less forgiving than whatever desktop browser you use. Particularly it is illegal to set style property of HTMLElement as string in strict mode. You may see examples of the ways to set it properly at https://developer.mozilla.org/en/docs/Web/API/HTMLElement/style If you fix this issue, code seems to be working on Mobile Safari as well.
P.S. note that the offending code is missing in your question and is only visible in the full code of writeResult on plunker. This is why it is so important to provide a Minimal, Complete, and Verifiable example
From your plunker, if you update your code on line 152 from newResultTitle.style = "color:rgba(238,62,52,.99);"; to newResultTitle.style.color = "rgba(238,62,52,.99)"; this would make it work on mobile browsers.
HTMLElement.style reruns a read only property, desktop browser ignoring it when you are trying to assign a value to it, and mobile browser throwing an error.

This question regarding a web app built using the ArcGIS Javascript API 3.18. I am trying to add an dojo select to the title of an infoWindow. The select box is intended to be populated with the list of identified results. I'm trying two different ways:
1) Adding the combobox declaratively using html:
var template = new esri.InfoTemplate(layerName + "<br/><select id="id_select" data-dojo-type="dijit/form/Select"</select>,"<br/> FID : ${FID}");
The combobox is there, but I don't know how to access the combobox to add the options dynamically (via addOptions). I would normally do dijit.byId("id_select"), but considering it doesn't exist until it's created...I'm not sure how to go about this way.
2) Programmatically
With the code below, the title displays information regarding the dijit/form/select widget (It displays: [object HTML TableElement]), but not the widget itself. Wondering if this can be rectified using dijitStartup(), but I can't haven't figured out how to use it (currently trying something along the lines of myTemplate.startupDijits(mySelectBox)--not with these variable names). I tried using domConstruct like this example
var identifyTask, identifyParams, idPoint;
var identifyResults;
require([
"esri/dijit/Popup",
"esri/tasks/IdentifyTask",
"esri/tasks/IdentifyParameters",
"dijit/form/Select",
"dojo/dom-construct",
"dojo/promise/all",
"dojo/domReady!"
], function (
Popup, IdentifyTask, IdentifyParameters, Select, domConstruct, All
) {
var identifySelect;
//dojo.connect(window.myMap, "onLoad", mapReady);
mapReady(window.myMap);
function mapReady(map) {
dojo.connect(window.myMap, "onClick", runIdentifies);
}
function runIdentifies(evt) {
identifyResults = [];
idPoint = evt.mapPoint;
var layers = dojo.map(window.myMap.layerIds, function (layerId) {
return window.myMap.getLayer(layerId);
});
layers = dojo.filter(layers, function (layer) {
if (layer.visibleLayers[0] !== -1) {
return layer.getImageUrl && layer.visible
}
}); //Only dynamic layers have the getImageUrl function. Filter so you only query visible dynamic layers
var tasks = dojo.map(layers, function (layer) {
return new IdentifyTask(layer.url);
}); //map each visible dynamic layer to a new identify task, using the layer url
var defTasks = dojo.map(tasks, function (task) {
return new dojo.Deferred();
}); //map each identify task to a new dojo.Deferred
var params = createIdentifyParams(layers, evt);
var promises = [];
for (i = 0; i < tasks.length; i++) {
promises.push(tasks[i].execute(params[i])); //Execute each task
}
var allPromises = new All(promises);
allPromises.then(function (r) { showIdentifyResults(r, tasks); });
}
function showIdentifyResults(r, tasks) {
var results = [];
var taskUrls = [];
var resultNames = [];
r = dojo.filter(r, function (result) {
return r[0];
});

results = results.concat(r[i]);
for (j = 0; j < r[i].length; j++) {
taskUrls = taskUrls.concat(tasks[i].url);
}
}
results = dojo.map(results, function (result, index) {
var feature = result.feature;
var layerName = result.layerName;
var serviceUrl = taskUrls[index];
resultNames.push({
value: result.layerName,
label: result.layerName
});
feature.attributes.layerName = result.layerName;
var identifiedList = getIdentifiedList(resultNames);

var resultType = resultGeometry.type;

});
if (results.length === 0) {

} else {
window.myMap.infoWindow.setFeatures(results);
}
window.myMap.infoWindow.show(idPoint);
identifySelect.on('change', function(evt) {
var identIndex = identifySelect.get("value");
console.log(identIndex);
window.myMap.infoWindow.select(identIndex);
});
return results;
}
function getIdentifiedList(options) {
identifySelect = new Select({
name: "identifySelect",
id: "id_select",
options: options
}, domConstruct.create("select"));
return identifySelect.domNode;
}
function createIdentifyParams(layers, evt) {
var identifyParamsList = [];

dojo.forEach(layers, function (layer) {
var idParams = new esri.tasks.IdentifyParameters();
idParams.width = window.myMap.width;

Hi this is kinda old but i'll give it a shot. I hope this answers your question.
So if the problem is accessing the infoWindow what you need to do is set up a listener for when it is created.
on(map.infoWindow, "show", function () {
// do something
})
I have a fiddle that shows how to access infoWindow upon creation:

I'm really new to JS, and I'm now stuck on a task, hope someone can guide me through it.
I have an Array of Objects, like this one:
var labels = [
// labels for pag 1
{pageID:1, labels: [
{labelID:0, content:[{lang:'eng', text:'Txt1 Eng'}, {lang:'de', text:'Txt1 De:'}]},
{labelID:1, content:[{lang:'eng', text:'Txt 2 Eng:'}, {lang:'de', text:'Txt2 De:'}]},
{labelID:2, content:[{lang:'eng', text:'Txt 3 Eng:'},{lang:'de', text:'Txt 3 De:'}]}
]},
// labels for pag 2
{pageID:2, labels: [
{labelID:0, content:[{lang:'eng', text:'Txt1 Eng'}, {lang:'de', text:'Txt1 De:'}]},
{labelID:1, content:[{lang:'eng', text:'Txt 2 Eng:'}, {lang:'de', text:'Txt2 De:'}]},
{labelID:2, content:[{lang:'eng', text:'Txt 3 Eng:'},{lang:'de', text:'Txt 3 De:'}]}
]}
]
What I am trying to do is write a function to return me an array of labels (Objects) for a specific page and a specific lang. By calling this function specifying pageID 1 and lang eng, I'm basically trying to build an array like this one:
var desideredArray = [
{labelID:0, text:'Txt1 Eng'},
{labelID:1, text:'Txt1 Eng'},
{labelID:2, text:'Txt2 Eng'}
]
Now, I'm trying to write the function to retrieve/build the new array:
this.getLabelsForPageAndLang = function (numPage, lang) {
// this part filters the main object and selects the object with pageID == numPage
var result = labels.filter(function( obj ) {
return obj.pageID == numPage;
});
var tempResult = result[0].labels;
var desiredResults = []; // here I want to store the new objects
for (var i=0; i<tempResult.length; i++) {
var simpleLabelObject = {};
simpleLabelObject.labelID = tempResult[i].labelID;
// simpleLabelObject.text = ?????
results[i] = simpleLabelObject;
}
console.log (results);
};
...but how can I access the right value (the one corresponding the lang selected) in the content property?
You can use the same technique as the one used to keep the matching page: the filter method.
this.getLabelsForPageAndLang = function (numPage, lang) {
// this part filters the main object and selects the object with pageID == numPage
var result = labels.filter(function( obj ) {
return obj.pageID == numPage;
});
var contentFilter = function(obj){ return obj.lang === lang};
var tempResult = result[0].labels;
var desiredResults = []; // here I want to store the new objects
for (var i=0; i<tempResult.length; i++) {
var simpleLabelObject = {};
simpleLabelObject.labelID = tempResult[i].labelID;
var matching = tempResult[i].content.filter(contentFilter);
simpleLabelObject.text = matching[0].text;
desiredResults[i] = simpleLabelObject;
}
console.log (desiredResults);
};
I didn't do bound checks because in your code you assumed there is always a matching element, but it would probably be wise to do it.
And if you want to avoid creating two closures each time the function is called, you can prototype an object for that:
var Filter = function(numPage, lang) {
this.numPage = numPage;
this.lang = lang;
};
Filter.prototype.filterPage = function(obj) {
return obj.pageID === this.numPage;
}
Filter.prototype.filterLang = function(obj) {
return obj.lang === this.lang;
}
Filter.prototype.filterLabels = function(labels) {
var result = labels.filter(this.filterPage, this);
var tempResult = result[0].labels;
var desiredResults = []; // here I want to store the new objects
for (var i=0; i<tempResult.length; i++) {
var simpleLabelObject = {};
simpleLabelObject.labelID = tempResult[i].labelID;
var matching = tempResult[i].content.filter(this.filterLang, this);
simpleLabelObject.text = matching[0].text;
desiredResults[i] = simpleLabelObject;
}
return desiredResults;
}
console.log(new Filter(1, "eng").filterLabels(labels));
Just filter again:
var getLabelsForPageAndLang = function (numPage, lang) {
// this part filters the main object and selects the object with pageID == numPage
var result = labels.filter(function (obj) {
return obj.pageID == numPage;
});
var tempResult = result[0].labels;
var desiredResults = []; // here I want to store the new objects
for (var i = 0; i < tempResult.length; i++) {
var simpleLabelObject = {};
simpleLabelObject.labelID = tempResult[i].labelID;
var lg = tempResult[i].content.filter(function (lg) {
return lg.lang == lang;
});
simpleLabelObject.text = lg[0].text;
desiredResults.push(simpleLabelObject);
}
console.log(desiredResults);
};
http://jsfiddle.net/9q5zF/
A rather 'safe' implementation for cases when pages have the same pageID and multiple contents with the same lang:
this.getLabelsForPageAndLang = function(numPage, lang) {
var result = [];
var pages = labels.filter(function( obj ) {
return obj.pageID === numPage;
});
for (var p = pages.length - 1; p >= 0; p--) {
var page = pages[p];
for(var i = page.labels.length - 1; i >= 0; i--) {
var labelId = page.labels[i].labelID;
for (var j = page.labels[i].content.length - 1; j >= 0; j--){
if (page.labels[i].content[j].lang === lang) {
result.push({labelID: labelId, test: page.labels[i].content[j].text});
}
}
}
}
console.log(result);
}
