  • Confirm box always displays first (javascript, jQuery, .Net)

    - by Jan-Frederik Carl
    Hello, I have a jQuery-Script to accomplish the following tasks: if a gridview in my form contains a row with a certain id, it has to be marked red. a confirm dialogue has to pop up to ask the user if he wants to do this or that. I built this code: if (response == "EntryInList") { $('#entryListContainer div table tbody tr').each(function() { if ($(this).attr('id') == 'entry_' + $('#<%= txtProductNumber.ClientID %>').val()) { $(this).css("color", "red"); } } ); if (!confirm("Entry already exists. Really overwrite?")) { jQuery('#<%= txtProductNumber.ClientID %>').val(''); jQuery('#<%= txtCount.ClientID %>').val(''); jQuery('#<%= txtProductNumber.ClientID %>').focus(); return false; } } As a result, the confirm box pops up first, without the row being turned red. Only after using the box, it becomes red. How would I get the row to be turned red at once? Another of my problems is that the confirm box denies my page to be scrolled down. But I would like to do this if the gridview is longer than the entire page.

  • JavaScript, transform object into array

    - by Šime Vidas
    I've got an object: var obj = { "Mike": 24, "Peter": 23, "Simon": 33, "Tom": 12, "Frank": 31 }; I want to create an array that holds the values of the object. The keys (key names) can be disregarded: [24, 23, 33, 12, 31] The order of the values is NOT important! One solution (obviously) would be do have a function that takes the values and puts them into an array: var arr = valuesToArray(obj); I will accept such a function as the answer. However, I would be more pleased if there would be an API function (ECMAScript, jQuery, browser-specific, ...) that could do this. Is there such a thing?

  • Loading and removing images with DOM, Javascript

    - by jesse
    I'm new to DOM and I'm having trouble removing multiple images that I loaded this loads 7 images (1.jpg, 2.jpg, etc..) function loadImages() { for (var i = 1; i < 8; i++ ) { var img = document.createElement("img"); img.src = "images/"+i+".jpg"; var idName = "img"+i+""; document.getElementById(idName).appendChild(img); } } this should remove all of them, but doesn't.. I think it breaks at the removeChild line. function removeImages() { for (var i = 1; i < 8; i++ ) { var idName = "img"+i+""; var d = document.getElementById(idName); d.removeChild(document.getElementById(img)); } } I think I'm doing something fundamentally wrong, because I don't fully understand how this works...

  • javascript watching for variable change via a timer

    - by DA
    I have a slide show where every 10 seconds the next image loads. Once an image loads, it waits 10 seconds (setTimeout) and then calls a function which fades it out, then calls the function again to fade in the next image. It repeats indefinitely. This works. However, at times, I'm going to want to over-ride this "function1 call - pause - function2 call - function1 call" loop outside of this function (for instance, I may click on a slide # and want to jump directly to that slide and cancel the current pause). One solution seems to be to set up a variable, allow other events to change that variable and then in my original function chain, check for any changes before continuing the loop. I have this set up: var ping = 500; var pausetime = 10000; for(i=0; i<=pausetime; i=i+ping){ setTimeout(function(){ console.log(gocheckthevariable()); console.log(i); pseudoIf('the variable is true AND the timer is done then...do the next thing') },i) } The idea is that I'd like to pause for 10 seconds. During this pause, every half second I'll check to see if this should be stopped. The above will write out to the console the following every half second: true 10000 true 10000 true 10000 etc... But what I want/need is this: true 0 true 500 true 1000 etc... The basic problem is that the for loop executes before each of the set timeouts. While I can check the value of the variable every half second, I can't match that against the current loop index. I'm sure this is a common issue, but I'm at a loss what I should actually be searching for.

  • Javascript "inlet" or "offset" function for drop-list options

    - by Camran
    I have seen on several sites that drop list values can have offsets... For example this drop-list: Fruits Apple Banana Orange Colors Red White Black The above are all options, but some have "inlets" or "offsets" or whatever you want to call it. How is this done with js? (regular js, not jquery at the moment) Thanks If you need more input let me know.

  • Write a row to Google Spreadsheet programmically javascript

    - by Verber
    I'm trying to find a way to insert a row into a google spreadsheet dynamically. I have a list of objects that has all the data for every column in a row. I'm just trying to run a for loop and then send the data to the row in the spread sheet. But the spreadsheet is completely empty. So I don't know if that creates certain problems or not. for(var j=0; j < masterList.length; j++) { //tried this one but it didn't pan out sheet.appendRow([ masterList[j].Date, masterList[j].Name, masterList[j].Bugs, masterList[j].Enhancements, masterList[j].Epic, masterList[j].DevOps, masterList[j].High ]); }

  • Javascript Recursion

    - by rpophessagr
    I have an ajax call and would like to recall it once I finish parsing and animating the result into the page. And that's where I'm getting stuck. I was able to recall the function, but it seems to not take into account the delays in the animation. i.e. The console keeps outputting the values at a wild pace. I thought setInterval might help with the interval being the sum of the length of my delays, but I can't get that to work... function loadEm(){ var result=new Array(); $.getJSON("jsonCall.php",function(results){ $.each(results, function(i, res){ rand = (Math.floor(Math.random()*11)*1000)+2000; fullRand += rand; console.log(fullRand); $("tr:first").delay(rand).queue(function(next) { doStuff(res); next(); }); }); var int=self.setInterval("loadEm()",fullRand); }); } });

    - by Anil Namde
    I have table cell which has class "cellActive". Which has following defination .cellActive{background:"#DDDDDD"} Now i am trying to read the background color property for the cell and it comes null/"". var bgColor = cell.style.backgroundColor; // returning "" Is that something mistake on my part of its by behavior. If CSS class is assigning CSS to element can't we read its value in JS ? Does this mean that if we are not assigning property directly to the element we cant get it if in case its inheriting it ?

  • http post request with cross-origin in javascript

    - by Calamarico
    i have a problem with a http post call in firefox. I know that when there are a cross origin, firefox first do a OPTIONS before the POST to know the access-control-allow headers. With this code i dont have any problem: Net.requestSpeech.prototype.post = function(url, data) { if(this.xhr != null) { this.xhr.open("POST", url); this.xhr.onreadystatechange = Net.requestSpeech.eventFunction; this.xhr.setRequestHeader("Content-Type", "application/json; charset=utf-8"); this.xhr.send(data); } } I test this code with a simple html that invokes this function. Everything is ok and i have the response of the OPTIONS and POST, and i process the response. But, i'm trying to integrate this code with an existen application with uses jquery (i dont know if this is a problem), when the send(data) executes in this case, the browser (firefox) do the same, first do a OPTION request, but in this case dont receive the response of the server and puts this message in console: [18:48:13.529] OPTIONS http://localhost:8111/ [undefined 31ms] Undefined... the undefined is because dont receive the response, but the code is the same, i dont know why in this case the option dont receive the response, someone have an idea? i debug my server app and the OPTIONS arrive ok to the server, but it seems like the browser dont wait to the response. edit more later: ok i think that the problem is when i run with a simple html with a SCRIPT tag that invokes the method who do the request run ok, but in this app that dont receive the response, i have a form that do a onsubmit event, i think that the submit event returns very fast and the browser dont have time to get the OPTIONS request. edit more later later: WTF, i resolve the problem make the POST request to sync: this.xhr.open("POST", url, false); The submit reponse very quickly and can't wait to the OPTION response of the browser, any idea to this?

  • If Else Conditionals within Function in JavaScript

    - by Antoine-Laurent Lavoisier
    I'm having issues with conditionals. I want to return the index where pattern starts in string (or -1 if not found). The search is to be case sensitive if the 3rd parameter is true otherwise it is case insensitive. Examples index("abAB12","AB",true) returns 2 but index("abAB12","AB",false) returns 0 index("abAB12","BA",true) returns -1 and index("abAB12","BA",false) returns 1 Any idea how I can accomplish this? This is my code so far var s = "abAB12" var p = "AB" var cs = true function index(string, pattern, caseSensitive) { if (pattern) { var found = false; if (caseSensitive = false) { if (string.indexOf(pattern.) >= 0) { found = true; } return (found); else { return (""); } } else if (caseSensitive = true) { if (string.toLowerCase().indexOf(pattern.toLowerCase()) >= 0) { found = true; } return (found); } else { return (""); } } } alert(index(s, p, cs)); Fiddle at http://jsfiddle.net/AfDFb/1/

  • JavaScript/jQuery: Follow path over page

    - by Echilon
    I need to make an animated gif 'fly over a page and follow a path. I'm thinking of using jQuery but would I be right in thinking the only way to do it is manually calculating the percentage of width/height where the shape layer should be placed, then using absolute positioning is the only way to do this? I know there are some amazing jQuery plugins available for this type of thing.

  • window.location alternatives in JavaScript

    - by MartyIX
    What is a standardized alternative to window.location.href function? I was checking on w3schools.com that it is implemented in all major browsers so there's no problem but I'm rather curious how to do that properly. From here is the statement that the function is not standardized: https://developer.mozilla.org/en/DOM/window.location Thanks!

  • JavaScript - question regarding data structure

    - by orokusaki
    I'm trying to calculate somebody's bowel health based on a points system. I can edit the data structure, or logic in any way. I'm just trying to write a function and data structure to handle this ability. Pseudo calculator function: // Bowel health calculator var points = 0; If age is from 30 and 34: points += 1 If age is from 35 and 40: points += 2 If daily BMs is from 1 and 3: points -= 1 If daily BMs is from 4 and 6: points -= 2 return points; Pseudo data structure: var points_map = { age: { '30-34': 1, '35-40': 2 }, dbm: { '1-3': -1, '4-6': -2 } }; I have a full spreadsheet of data like this, and I am trying to write a DRY version of code and a DRY version of this data (ie, probably not a string for the '30-34', etc) in order to handle this sort of thing without a humongous number of switch statements.
