JavaScript - Need To Find Index Of Object In Multidimensional Array
I have an array "arr" that is an array of objects. Each object has the same 7 properties.
I want to find the index of the object with a property that matches a certain value x in the array arr. How can i accomplish this? The array has hash tables associated with it. arr [ obj [ i ] . property1 + "_" + obj [ i ] . property2 ] = arr [ i ] ; so whats the index of the object where .property1 = x ? Thanks, g Similar TutorialsI'm new to Javascript, and am having a bit of trouble figuring out some things... so hopefully this will be an easy one. I want a lookup table that matches url fragments to the name I want to show. For instance, if a url contains "yahoo.com", I want to print "Yahoo." For now, I created a multidimensional array that maps url fragments to a name. such as, Code: var urlMapping = [ { urlpath: "yahoo.com", mapto: "Yahoo"}, { urlpath: "google.com", mapto: "Google"} ]; So, say I have a variable urlVar, where the value is some URL (for example, "http://us.mg201.mail.yahoo.com"). Is there any way - other than looping through the array for every variable - to check if urlVar contains any of the substrings in urlMapping.urlPath, and if so, output urlMapping.mapto? (In this case, I want urlVar to find that it contains the substring "yahoo.com" and output "Yahoo".) In my code, I anticipate that I have 100 variables checked against 50 mappings, and performance is important to me. Thanks in advance! Hi, I am trying to save information to a multidimensional associative array, when a use inputs data about booking a restaurant table. So basically if he user changes his/her mind and cancels but wants to retrieve that information again at the same time they can do so. So for example the information would be like: - Code: Table 1 Customer Name Time Seats Table 2 Customer Name Time Seats etc. Now what I want to know is how do I implement this as a multi-associative array and how do I retrieve the values. I'm writing a program that involves a network of interconnected nodes (or simply objects in my example below). It depends on being able to access properties of an object's linked objects (a bit oddly worded, sorry)... Problem is I'm not sure how to properly access those properties... see below please. <script> //This is an example of a problem im having in my own code... //I want to access the name of the object within the links array wintin the object... var objA = {name: "Object A", links: [objB, objC]}; var objB = {name: "Object B", links: [objC, objD, objE]}; var objC = {name: "Object C", links: [objB]}; var objD = {name: "Object D", links: [objE]}; var objE = {name: "Object E", links: [objD]}; //ex: I want to access the name of Object A's first link... console.log(objA.links[0].name); </script> I'm hoping to get "Object B"... But instead I get: TypeError: Result of expression 'objA.links[0]' [undefined] is not an object. Is there another way around this? Any thoughts are appreciated. I have the following array called 'datacontent' that have the following data: (4, RX33, ) (3, RX54, ) (102, RX44, ) (1, R100, Retail Branch 100) (2, RX12, ) (100, RX55, ) I want them to be sorted into this order: (1, R100, Retail Branch 100) (2, RX12, ) (3, RX54, ) (4, RX33, ) (100, RX55, ) (102, RX44, ) But it is always not sorted and it will give me as follows: (2, RX12, ) (3, RX54, ) (4, RX33, ) (100, RX55, ) (102, RX44, ) (1, R100, Retail Branch 100) My code is as follows: Code: function sortby(i) { return function(a,b){a = a[i];b = b[i];return a.toLowerCase() == b.toLowerCase() ? 0 : (a.toLowerCase() < b.toLowerCase() ? -1 : 1)} } datacontent.sort(sortby(1)); Appreciate any help. I have the following code as shown below: Code: <html> <script type="text/javascript"> var all = []; var a = ["1234", "Jim", "Lab1", "5455"]; var b = ["1235", "Jack", "Lab1", "5459"]; var c = ["1236", "Jane", "Lab1", "5455"]; var d = ["1237", "June", "Lab1", "5458"]; var e = ["1238", "Jill", "Lab2", "5461"]; var f = ["1239", "John", "Lab2", "5462"]; var g = ["1240", "Jacab", "Lab3", "5465"]; all.push(a); all.push(b); all.push(c); all.push(d); all.push(e); all.push(f); all.push(g); for(var i=0; i<all.length; i++){ document.write(all[i] + "<br>"); } </script> </html> How to I get the unique & in order of column 4 given that column 3 is given.

Hi, I'm struggling with all this DOM stuff so I hope someone can help. I have a form with multiple input fields and I'm trying to identify the specific input field that is in focus so that I can display a relevant status bar message. I have a message array with various entries in it and I'm calling a showStatus() function with an onfocus function from the form itself e.g. The code in the input form = Code: <input type="text" name="first" size="31" maxlength="20" class="entry" onfocus="showStatus()"/> The showStatus() function so far is = Code: function showStatus() { var message = ['Please provide your First Name.', plus loads of other properley formatted status messages......] var x=document.getElementById().focus(); window.status = message[x]; } I'd like to access the array variable of the item that is in focus not only for the message but also for an onblur function to validate input.

Hi all, I am trying to build a config object for a program using a loop. Here's what I've done so far (note: "bbtags" is an array built like this): var bbtags = new Array((b),(/b),(i),(/i),(u),(/u),etc......); (note I used parentheses in place of brackets soas not to confuse the board.) Code: var arr = []; var len = bbtags.length; var tag = ''; var obj = ''; for (var i = 0; i < len; i+=2) { tag = bbtags[i].replace(/\[(.*?)\]/gi,'$1'); // strip off the brackets name = String('mce_' + tag); // generate a name obj = { name : { 'block' : name } } arr.push(obj); } The RESULT that I am after would look like this: Code: mce_b : { 'block' : 'mce_b' }, mce_i : { 'block' : 'mce_i' }, mce_u : { 'block' : 'mce_u' }, etc....... Notice the items I marked in red. Instead of these items having the VALUE of the variable "name", they instead have value of "name". That is, every part in red is "name". Any ideas how to make this work right (or an idea how to do it BETTER)? Thanks! -- Roger I am trying to parse a string so I can put points into google maps api. Here is the string i am using: Code: CountySide Town 66202 KS COUNTRYSIDE,39.025376,-94.766998|Shawnee City 66203 KS SHAWNEE,39.019802,-94.808303 Here is the javascript I am using: Code: var a = new Array(); function parseAddress(addressString) { alert(addressString); var prompt = addressString.split("|"); for (var i = 0; i < prompt.length; i++) { var details = prompt[i].split(","); var t = new Object(); t.name = details[0] t.lat = details[1] t.lng = details[2] a[i] = t; } } I have found if I do something like this: Code: var t = new Object(); t.name = "Shawnee" t.lat = 39.019802 t.lng = -94.708303 a[0] = t; var t = new Object(); t.name = "Overland Park" t.lat = 38.992488, t.lng = -94.674769 a[1] = t; It will work, can someone tell me why my loop doesnt work? Hi, I am trying to create an array to pass to JQuery, but after several hours of trying, am falling over. I am trying to use Ajax to populate the javascript FullCalendar. I am trying to pass an arry to the following property: This works: $('#calendar').fullCalendar({ events: [{"id":1112,"title":"Event1","start":"2009-10-10"},{"id":222,"title":"Event2","start":"2009-10-20","end":"2009-10-22"}] }; something like: $('#calendar').fullCalendar({ events: MyJSArray() }; I will be using AJAX to populate MyJSArray(). I have tried the likes of: MyJSArray = new array("id"=>112,"title"=>"Event1", etc); But no joy I don't know how to get a javascript array into that format. I have my database values, but I need to put them into a format that the "Event" will accept. I have used PHP and arrays fine, but coming to grips with JS arrays,etc are a bit finiky at the moment. I am a little stuck, any help or points in the right direction will be much appreciated. Thanks Blueevo. Hi I need help with spawning in my game. I have this code: Code: function spawnEnemy() { var shapes = [LeftBlock, RightBlock, middleRightBlock, middleLeftBlock, middleBlock]; var shape = shapes[Math.floor(Math.random() * shapes.length)]; var RandomBlock = new THREE.Object3D(); RandomBlock.add(shape); blocks.push(RandomBlock); for (var i = 0; i < blocks.length; i++) { RandomBlock = blocks[i]; scene.add(RandomBlock); hit = false; } } function startSpawningEnemies() { repeater = setInterval(function() { spawnEnemy(); newBlock = false; }, 1000); } Basically it chooses a random object in the array 'shapes' and it adds the shape to the scene every second. But the problem is that when I have, for example a 'Leftblock' on screen and it randomly gets called again, Leftblock will get reset to the starting position, so basically I cant have 2 of the same type of block on screen at once. So I want want every block in the array to be an entirely new instance of a block, rather than the same. Here is a code pen so you can see what is happening My Codepen Thanks in advance Reply With Quote 01-31-2015, 12:06 PM #2 Lesshardtofind View Profile View Forum Posts Visit Homepage New Coder Join Date Sep 2013 Location Houston Posts 20 Thanks 0 Thanked 4 Times in 4 Posts Hey I apologize in advance this will probably be a long post, but to get to the root of your problem it takes a bit of explaining to show how I fixed it. If you don't want to read about all the changes and why I did them if you scroll to the bottom of this post the last code snippet is the new working code. Firstly I'd like to make a few comments. 1. Try to avoid using so many globals that is what is confusing the whole thing. 2. Even though JavaScript isn't a classical language. Using some OOP approaches can simplify your code quite a bit. Now to what your actual problem was. You only had one instance of meshes for each type of block/paddle or whatever you call it. Even though you created new 3d objects you still were just passing it the values of the current existing Meshes. In order to get around this I simplified your code a lot. I removed around 200 lines of code and created a few objects to make things easier. I don't know that I can explain every single thing I did, but creating objects is very useful for instance instead of making a ton of variables for each box you can make an Object called Box and then create a new instance of it. Since your Box also needs a mesh you can create that inside of the box as well. Code: function Box(w, h, d, q, m){ var CoreInfo = { width: w, height: h, depth: d, quality: q, material: m }; var Mesh = GetNewMesh(CoreInfo); this.setMeshY = function(y){ Mesh.position.y = y; } this.setMeshX = function(x){ Mesh.position.x = x; } this.getCoreInfo = function(key){ return CoreInfo[key]; } this.setCoreInfo = function(key, val){ CoreInfo[key] = val; } this.getAllInfo = function(){ return CoreInfo; } this.getMesh = function(){ return Mesh; } this.setShadows = function(r, c){ Mesh.receiveShadow = r; Mesh.castShadow = c; } } // you will notice that it calls this to get a MESH instead of using 5+ serperate calls you can now wrap it into a function that takes an assoc array. function GetNewMesh(info){ var Q = info["qaulity"]; return new THREE.Mesh( new THREE.BoxGeometry( info["width"], info["height"], info["depth"], Q, Q, Q), info["material"]); } With this object you can create new instances of boxes just by passing all the variables it needs and save it into a new object. example use: Code: var BlockMat = new THREE.MeshLambertMaterial({color: 0x3c00ff}); var Abox = new Box(10, 160, 10, 1, BlockMat); As you can see the Box requires 5 arguments to construct. They are width, height, depth, quality, and material; You will also notice there are functions inside of the Box to call functionality they are setMeshY(y): This sets the Y position of the mesh as the y value passed to it; setMeshX(x): This sets the X position of the mesh as the x value passed to it; getCoreInfo(key): This gets some CoreInfo based on a string or "key" that you pass it. EX use Box.getCoreInfo("width"); setCoreInfo(key, value): This sets some CoreInfo based on a string or "key" that you pass it. EX use Box.setCoreInfo("width", 100); getAllInfo(): Returns ALL CoreInfo in an assoc array that is accessed by a "key." EX use var AllInfo = Box.getAllInfo(); AllInfo["width"]; getMesh: Returns The mesh object setShadows: Allows you to set shadows by passing true or false for the receive and cast arguments. Now some of your enemy boxes needed two boxes so I further created a object called Double Box; These are very much the same as a box. Just all methods need to be passed an index as well. These are identical to your original objects as Paddle1 is now at index 0, and Paddle2 is at index1 for each respective object. With those objects created we can Delete a TON of your global variables and clean some stuff up. As a matter of fact the more I looked at it you didn't even NEED globals for your set enemy paddle types at all. I was able to wrap them all up into a function that will return an object like you wanted by being passed a string. Code: function GetBlock(type){ if(type == "m"){ var temp = new DoubleBox(10, 75, 10, 1, BlockMat, 10, 75, 10, 1, BlockMat); var obj = new THREE.Object3D(); obj.add(temp.getMesh(0)); obj.add(temp.getMesh(1)) temp.setMeshX(0, fieldWidth/2); temp.setMeshY(0, -60); temp.setMeshX(1, fieldWidth/2); temp.setMeshY(1, 60); return obj; } else if(type == "mr"){ var temp = new DoubleBox(10, 30, 10, 1,BlockMat, 10, 110, 10, 1,BlockMat); var obj = new THREE.Object3D(); obj.add(temp.getMesh(0)); obj.add(temp.getMesh(1)); temp.setMeshX(0, fieldWidth/2); temp.setMeshY(0, -80); temp.setMeshX(1, fieldWidth/2); temp.setMeshY(1, 40); return obj; } else if(type == "ml"){ var temp = new DoubleBox(10, 30, 10, 1, BlockMat, 10, 110, 10, 1, BlockMat); var obj = new THREE.Object3D(); obj.add(temp.getMesh(0)); obj.add(temp.getMesh(1)); temp.setMeshX(0, fieldWidth/2); temp.setMeshY(0, 80); temp.setMeshX(1, fieldWidth/2); temp.setMeshY(1, -40); return obj; } else if(type == "l"){ var temp = new Box(10, 160, 10, 1, BlockMat); var obj = new THREE.Object3D(); obj.add(temp.getMesh()); temp.setMeshX(fieldWidth/2); temp.setMeshY(20); return obj; } else if(type == "r"){ var temp = new Box(10, 160, 10, 1, BlockMat); var obj = new THREE.Object3D(); obj.add(temp.getMesh()); temp.setMeshX(fieldWidth/2); temp.setMeshY(-20); return obj; } } While this could be cleaned up and do some extra error checking it now does EXACTLY what you need it to. You can call this function and pass it a string for each type of block you want. It will return a NEW instance of that type of block without sharing meshes as you had previously programmed it to. now you can call this function in the spawn enemy function Code: function spawnEnemy() //total enemies starts at 0 and every-time you add to array { var shapes = ["l", "r", "mr", "ml", "m"]; // these are the strings that pass to the GetBlock(type) function as type var shape = shapes[Math.floor(Math.random() * shapes.length)]; blocks.push(new THREE.Object3D().add(GetBlock(shape))); // now you just pass the function to the THREE.Object3d().add() accepting shape as a parameter. for (var i = 0; i < blocks.length; i++) { RandomBlock = blocks[i]; scene.add(RandomBlock); hit = false; } } I know I made a lot of changes and there are still plenty more that could reduce your code even further, but when I finally got to a point where it was working the way you wanted to I figured I'd hand it back over to you.

I also commented out the collision as you will need to think of a new method for doing that. Most likely just build a function that accepts an array and then just pass it your blocks array and let it loop through it. Overall cool game good luck to ya. Don't hesitate to reach out if you have any other questions.

I didn't expect such a huge reply, it seems that my original code has changed a lot and I will have to give it a hard look through it to understand it. I will contact you if I have any questions, I have a lot of work ahead of me. Thanks a lot Reply With Quote 01-31-2015, 04:45 PM #4 TeaAnyOne View Profile View Forum Posts New to the CF scene Join Date Jan 2015 Posts 4 Thanks 2 Thanked 0 Times in 0 Posts I suppose I do have one more question. How do I get the position.x of the Randomblocks. I tried using a for loop like this: for (var i = 0; i < blocks.length; i++) { if (blocks[i].position.x === Player.getMesh().position.x*2 && newBlock === false) { console.log("pass"); newBlock = true; if (hit === false) { score++; } else { score--; } } document.getElementById("scores").innerHTML = score; } } it works but it seems kind of buggy as it stops counting to 10 when it changes speed. Is there another way to retrieve the position?

You may be having problems because you never despawn enemies ultimately getting a huge number of 3d objects in your array blocks, or you may find your position requirement doesn't mathematically work with your speed up. Sometimes just using a few extra console.logs to track your numbers inside of functions that don't seem to be working can help you to get an idea of what values it is seeing for the numbers and when. It might make the problem super obvious. This more like shotgun debugging which is discouraged by many, but I found it to help a lot when I was first learning code. Ultimately you want to understand your logic in each function and how it can fail when you program it, and then use error checking to make sure no parameters get outside of your allowed variance.

Very well said! I have an array of objects that I would like to sort through and "join" objects that are the same. And if they are the same, I need to sum up the number value given for those two items. So I guess Im sorting through and maybe even recreating this array to get rid of duplicates while I tally quantities. Please see the screenshot of my array of objects to help understand better. The highlighted 'sPSPN' would indicate that it is a duplicate item and its 'fUnits' need to be totalled. in the end I would have a total of 3 objects, because 'sPSPN'= BT-221-44 would now be only one object with 'fUnits' = 35. Thanks! Hi all, I'm wondering if what I'm trying to do here is even possible but I'd appreciate your thoughts on it. Code: <script type="text/javascript"> function test() { var arrays = { one: ['1', '2', '3'], two: ['a', 'b', 'c'] } var foo = 'one'; alert(arrays.(foo)); } test(); </script> I've tried numerous variations of the alert line with evals, brackets and jQuery syntax but always seem to get the error: Code: XML filter is applied to non-XML value ({one:["1", "2", "3"], two:["a", "b", "c"]}) Which makes me think I'm either attempting something stupid or only missing my target slightly. The code will be running within a jQuery project up if that helps in any way. The following code snippet: (this.inputArray is already defined and initialized prior to this code sequence) if(this.inputArray.length >= 0) { this.inputArray[this.inputArray.length] = new Object(); this.inputArray[this.inputArray.length].type = 'pcDisp'; this.inputArray[this.inputArray.length].data = a; } the first line in the code block should create a new array item and initialize it with the various assigments in the next lines. But Firefox complains "this.inputArray[this.inputArray.length] is not defined". This is very disconcerting because the code has to create array items with different data based on conditionals. So I must be able to automatically create new items as necessary. I thought that javascript had 'late binding', but maybe that doesn't apply here. So, does anyone have a clue for me? Hello, I've made a JS code that declare events based on year, month and days. Each date represents an event. The code works well but I'd like to improve the declaration when several days with the same description are following to reduce declaration lines. Here's the actual working code: var events = [ >> {year: '2011', month: '11',day: '1',description: "test description",url: '',newpage: false,mark_as_event: false}, >> {year: '2011', month: '11',day: '2',description: "test description",url: '',newpage: false,mark_as_event: false}, >> {year: '2011', month: '11',day: '3',description: "test description",url: '',newpage: false,mark_as_event: false}, >> {year: '2011', month: '11',day: '4',description: "test description",url: '',newpage: false,mark_as_event: false}, //I would like replace the 4 lines here above by something like this: >>>>> {year: '2011', month: '11',(day: '1','2','3'),description: "test description",url: '',newpage: false,mark_as_event: false}, {year: '2011', month: '11',day: '11',description: "11 november",url: '',newpage: false,mark_as_event: false}, {year: '2012', month: '4',day: '30',description: "easter",url: '',newpage: false,mark_as_event: false}, {year: '2012', month: '5',day: '1',description: "1 mai",url: '',newpage: false,mark_as_event: false}, {year: '', month: '',day: '',description: "",url: '',newpage: true,mark_as_event: true} ]; var temp_date=new Array(); //init current month data var temp_url=new Array(); var temp_newpage=new Array(); var temp_mark_as_event=new Array(); for (var i = 0; i < events.length; i++) { //Current month data are used here if (events[i].year==cal_year && events[i].month==(cal_month + 1)){ temp_date[events[i].day]=events[i].description; temp_url[events[i].day]=events[i].url; temp_newpage[events[i].day]=events[i].newpage; temp_mark_as_event[events[i].day]=events[i].mark_as_event; } } Is it possible and how ? Thank you very much Gino Hello All, I have a string array in a class file that contains 5 values, which I need to display on the jsp page. but when I send it to the javascript it prints [Ljava.lang.String;@104f8b8 . what do i do about it. I am a new to javascript. Is there a way to get my array data from the response object. Please help. |
