Actually I am using ArcGIS API for JavaScript 4.7 and i have a custom internal layer . I want to get name of place particular area when draw polyline the column name is (PLC_NAME) . How to achieve that ?
Suppose I draw a area through polyline. In this area there are places . Now I need to get name of these places .
you can find the using code in below i am using the TileLayer.

OK, you can resolve the queries on the client or on the server. Depends on your task what options you can pick on.
If you are going to use a spatial query, like the one you mention, and you will apply it on a FeatureLayer, you could solve it on the client. This is a good solution because you already have the features, you are seeing them. Here you have a question whis this situation, how-to-get-get-name-of-hospital-or-street-in-particular-area-when-draw-polyline.
Now, If you need to query something that might not be in your extent (you don't have the features) or you are not using a FeatureLayer, you probably will need to command the server to do this. But don't worry the library has several tools to work with, like QueryTask.
Here you have the same example of the answer link before but using QueryTask.

To close I leave you this link to the documentation that explains very well all the possibilities, pros and cons.
In Phaser 2 we scale a simple by setting the scale property as explained in docs:
https://phaser.io/examples/v2/groups/group-scale
But there is no equivalent in Phaser v3.
The possible url https://phaser.io/examples/v3/groups/group-scale points to nothing. And if I do:
this.enemies = this.add.group();
this.enemies.scale.set(2, 2);
It throws:
Phaser v3.19.0 (WebGL | Web Audio) https://phaser.io
indexph.js:22 Uncaught TypeError: Cannot read property 'set' of undefined
What is the appropriate form to scale a group of sprites in Phaser 3?
The code below should work, I think, But it doesn't.... it doesn't scale objects that are created from the group:
preload() {
this.load.atlas("sprites", "assets/spritesheet.png", "assets/spritesheet.json")
}
create() {
this.enemies = this.add.group({
key: 'sprites' ,
setScale: { x: 0.1, y: 0.1 }
});
this.enemies.create(60, 60, 'sprites', 'hamburguer.png');
In Phaser 3, you can scale a group by modifying the GroupConfig object passed in when you declare your group.
GroupConfig API Reference. You can see also see a live demo here.
In your case, to scale this group you should simply create it like:
this.enemies = this.add.group({
setScale: { x: 2, y: 2}
});
Alternatively, you could iterate through the group once it's created and scale each child object independently.
this.enemies = this.add.group();
this.enemies.children.iterate((child) => {
child.setScale(2, 2);
});

When rendering to pdf, I need the html page to be 100% of the print width. Otherwise content gets cut off. Is there an easy way to do this?
I came up with a work-around, which gets the html width after rendering and then sets the zoom factor to force the correct width.
var page = require('webpage').create(),
system = require('system'),
dpi = 89.9, // strange, but that's what I get on Mac
pageWidth = 210; // in mm
var getWidth = function() {
return page.evaluate(function() {
// get width manually
// ...
return width;
});
};
page.paperSize = {format: 'A4', orientation: 'portrait'};
page.open(system.args[1], function (status) {
window.setTimeout(function () {
page.zoomFactor = (pageWidth / 25.4) * dpi / getWidth();
page.render(system.args[2]);
phantom.exit();
}, 200);
});
Looking for a straight forward solution, because getting the width requires me to do some tricks due to the framework I use.
Managed to solve this by adding the following CSS rule which will zoom out the page and make it fit:
html {
zoom: 0.60;
}
Edit rasterize.js as follows.
Make a backup of rasterize.js
Remove this block (approx. line 18-31)
if (system.args.length > 4) {
page.zoomFactor = system.args[4];
}
page.open(address, function (status) {
if (status !== 'success') {
console.log('Unable to load the address!');
phantom.exit();
} else {
window.setTimeout(function () {
page.render(output);
phantom.exit();
}, 200);
}
});
Replace it with this code block
if (system.args.length > 4) {
page.zoomFactor = parseFloat(system.args[4].split("=")[1]);
}
page.open(address, function (status) {
if (status !== 'success') {
console.log('Unable to load the address!');
phantom.exit(1);
} else {
window.setTimeout(function () {
console.log("zoomFactor: " + page.zoomFactor);
page.evaluate(function(zoom) {
return document.querySelector('body').style.zoom = zoom;
}, page.zoomFactor); // <-- your zoom here
page.render(output);
phantom.exit();
}, 200);
}
});
Then you can export html to pdf on-the-fly like this:
~/bin/phantomjs ~/bin/phantomjs/examples/rasterize.js \
'http://example.com/index.html' \
mysite.pdf paperformat=A4 zoom=0.4
Let's say I have the following code
var $variable = $('<li/>', {
tabindex: 0,
click: function() {
//more code in here
}
}
is it possible to define the click: with a variable? Baring in mind it is already inside a variable and will also include an if statement, like so:
if(condition) {
var functiontype = 'click';
}
else {
var functiontype = 'hover';
}
var $variable = $('<li/>', {
tabindex: 0,
functiontype: function() {
//more code in here
}
}
I tried doing this but it didn't work. Can someone please point me in the right direction?
if(condition) {
var functiontype = 'click';
}
else {
var functiontype = 'hover';
}
var options = {};
options["tabindex"] = 0;
options[functiontype] = function(){
// your code
}
var $variable = $('<li/>', options);
You may do the reverse :
var $variable = $('<li/>', {
tabindex: 0
};
$variable[condition?'click':'hover'] = function(){
// the code here
}
I have a search page in which I am displaying properties from my database as markers in google map. Now I want to modify this search page so that any user will draw either a circle or polygon in the google map and will get properties from our database only in the selected area (drawn by user itself). I am attaching my code so far here.
The circle in the image shows the selected area and the result must display properties available in the selected region. My table contains 2 different fields for latitude and longitude of each property.

// map is clicked.
google.maps.event.addListener(drawingManager, 'drawingmode_changed', clearSelection);
google.maps.event.addListener(map, 'click', clearSelection);
google.maps.event.addDomListener(document.getElementById('delete-button'), 'click', deleteSelectedShape);
google.maps.event.addDomListener(document.getElementById('delete-all-button'), 'click', deleteAllShape);

The code above contains some events to handle the user interaction in search page to draw cirle,polygone to search property in selected region.
The display property button in the image must show property markers in the selected area.
How would I get the latitude and longitude of selected area of circle or polygon?
How Would I query my database for that range of co-ordinates?
Thanking you very much in advance for your kind help...
I suppose you have found a solution since you post this question.
However, if someone else needs an answer, this is how you can get lat / lng of a drawing polygon :
google.maps.event.addDomListener(drawingManager, 'polygoncomplete', function(polygon) {
var polygonBounds = polygon.getPath();
}
The bounds of each vertices of your polygon are now in polygonBounds, just iterate over it and do what you want with lat / lng
For a circle, you just need lat / lng of the center, and its radius
google.maps.event.addListener(drawingManager, 'circlecomplete', function(circle) {
var radius = circle.getRadius();
var center = circle.getCenter();
}
Hope it can help someone
PS : I'm using GoogleMaps v3.14, I never test with other versions.
