  • How to dynamically add a Javascript function (and invoke)

    - by whitey
    Based on a click event on the page, via ajax I fetch a block of html and script, I am able to take the script element and append it to the head element, however WebKit based browsers are not treating it as script (ie. I cannot invoke a function declared in the appended script). Using the Chrome Developer Tools I can see that my script node is indeed there, but it shows up differently then a script block that is not added dynamically, a non-dynamic script has a text child element and I cannot figure out a way to duplicate this for the dynamic script. Any ideas or better ways to be doing this? The driving force is there is potentially a lot of html and script that would never be needed unless a user clicks on a particular tab, in which case the relevant content (and script) would be loaded. Thanks!

  • Accessing HTML DOM elements from javascript using `.childNodes`

    - by Martin
    I'm wondering about the .childNodes property, I have the code below, and for some reason I get 18 children, while 6 are HTMLInputElements as expected, and the rest are undefined. What is this about? Is there an efficient way to iterate over the input elements? <html> <head> <script> window.onload = function(e){ form = document.getElementById('myForm'); alert(form.childNodes.length); for(i=0; i<form.childNodes.length; i++){ alert(form[i]); } } </script> </head> <body> <form id='myForm' action="haha" method="post"> Name: <input type="text" id="fnameAdd" name="name" /><br /> Phone1: <input type="text" id="phone1Add" name="phone1" /><br /> Phone2: <input type="text" id="phone2Add" name="phone2" /><br /> E-Mail: <input type="text" id="emailAdd" name="email" /><br /> Address: <input type="text" id="addressAdd" name="address" /><br /> <input type="submit" value="Save" /> </body> </html>

  • Javascript clone form?

    - by user202987
    I need to copy a form information with all types of elements and send it with AJAX. Tried these: 1. cloneNode on the form. - Doesn't work with IE, only copies text stuff properly. cloneNode on each element. Doesn't work with IE, only copies text stuff properly. Making new textareas for each element, and copying the value in. Doesn't work for textareas in IE, formatting is lost. I imagine a combination of those 3 would work for IE and FF but is there any decent solution to this? Shortness of code is a priority.

  • Javascript/Jquery - Reset text box view area after tab

    - by JK
    I don't know what this is called so its hard to google for it. If you have a plain html input type=text with a small width eg 20 and then type more characters than can be displayed, it shows the last characters you type. And the first ones are scrolled out of view: This is my long text // this is the whole string my long string // this is what is actually visible in the input box How do I make it so that when you hit tab, the view area resets so that the start of the string is visible and the end is hidden? my long string // this is what is visible in the input box when typing This is my // this is what is I want to be visible in the input box after you hit tab What do you call this, and how do you do it?

  • IE incompatibility with JavaScript (surprised?)

    - by Midevil Chaos
    I am coding my website, and a friend of mine was helping me. This code does not work on IE 10 (Windows 7). I even tried the legacy modes and to no avail. Upon clicking on "services" for example, this code would work on FF or Chrome. But, not on IE. Can someone help me fix this code so it would also work on IE? $('#services-fr-2').on('click',function(){ $( ".clientsFr" ).hide(); $('.servicesFr').fadeToggle(); $('#green-pouch-fr').animate({ 'top':'450px'//, //'height':'450' })

  • Android browser javascript events when minimised

    - by Sirber
    I'm building a webapp for Android smartphones that runs with the OS internet browser. the main interface is to input datas. the data is added to a queue (android 1.5: gears, android 2.x: html5). Each 5 minutes (using setTimeout), the script looks if an internet connection is active, and if so, sends all the queue to the server. If the phone is plugged on the wall and the webpage is ontop, the timeout works. if the browser is minimized or another application runs on top of it, the timeout doesn't work. if the phone is in sleep mode it doesn't work either. can only native apps runs in background?

  • JavaScript: how to use data but to hide it so as it cannot be reused

    - by loukote
    Hi all. I've some data that i'd like to publish just on one website, ie. it should not be reused on other websites. The data is a set of numbers that change every day, our journalists work to get hard gather it. Is there any way to hide, crypt, etc. the data in a way that it cannot be reused by others? But to show it in a graph in the same time? I found the ASCII to HEX tool that could be used for (http://utenti.multimania.it/ascii2hex/). I wonder if you can suggest other ways. (Even if I have to completely change the strategy.) Many thanks!

  • Adding an additional click event to every element (JavaScript / jQuery)

    - by Gausie
    I'm developing a touchscreen application that, aside from everything else, records the amount of times the screen is used so that the user can be reminded to clean the screen after a predefined number of clicks. I've got the click functions written nicely, all I need now is make sure the function is called on a click. I imagine $('*').click(function() { //do something }); would accomplish my goal, but is that the best way? Also, would that overwrite other click functions assigned to the elements?

  • JavaScript - Loop over all a tags, add an onclick to each one

    - by tripRev
    I've got a list of links that point to images, and a js function that takes a URL (of an image) and puts that image on the page when the function is called. I was originally adding an inline onlick="showPic(this.getAttribute('href'))" to each a, but I want to separate out the inline js. Here's my func for adding an onclick to each a tag when the page loads: function prepareLinks(){ var links = document.getElementsByTagName('a'); for(var i=0; i<links.length; i++){ var thisLink = links[i]; var source = thisLink.getAttribute('href'); if(thisLink.getAttribute('class') == 'imgLink'){ thisLink.onclick = function(){ showPic(source); return false; } } } } function showPic(source){ var placeholder = document.getElementById('placeholder'); placeholder.setAttribute('src',source); } window.onload = prepareLinks(); ...but every time showPic is called, the source var is the href of the last image. How can I make each link have the correct onclick?

  • Javascript + IFrame + Chrome + Https = strange issue

    - by GuiDoody
    Using a modal plugin for jquery, I'm opening an iframe in a modal with a click event and setting the source attribute to a relative url (should be within https). The page containing the click is an authenticated ssl page. In IE and Safari, this works as expected. In Chrome and Firefox, the source url is opened in http not https. If I set the source to an absolute url using https, same result. Example: // This doesn't work - resolves to http $('.lnkViewDetails').click(function(e){ var src = "/ThePage"; $.modal('<iframe src="' + src + '" height="500" width="425" style="border:0" frameborder="no">'); }); // This doesn't work - also resolves to http $('.lnkViewDetails').click(function(e){ var src = "https://MySite.com/ThePage"; $.modal('<iframe src="' + src + '" height="500" width="425" style="border:0" frameborder="no">'); }); Anyone know a way to get around this?

  • Javascript : random number between variables issue

    - by Mayhem
    I've seen the other examples on this site but I just can't get it to work. I'm trying to generate a random number between 2 user input variables on a form. The numbers will always be positive numbers. min = document.getElementById('min').value; max = document.getElementById('max').value; waitTimer = Math.floor(Math.random() * (max - min + 1)) + min; When min = 5 / max = 10, waitTimer is sometimes returning results like 2, 4 and 28 and so on. What am I doing wrong?

  • Javascript function returning number with two decimals...?

    - by muzzledBYbrass
    I have a function to return points along a line and my return comes back with two decimal points...? For example, a return of my variable px will be something like -88.4029.032940598. vx is the x vector and mult is the distance of the line plus distance to calculate the point. Here is the operation that is returning these values: var mult = parseFloat(mag + theUnit); var px = coord_one.x_point + (vx * mult); console.log(px); Never have seen this before- I appreciate any and all help!

  • Split a sting array into a number array in javascript

    - by Wesley Skeen
    I am reading a value from a dropdown list depending on what option is selected. I am using jqPlot to graph the values. jqPlot expects an array of values like [91, 6, 2, 57, 29, 40, 95] but when I read the value in from the dropdown box it is coming in as a whole string "[91, 6, 2, 57, 29, 40, 95]" I tried splitting it but I got ["91", "6", "2", "57", "29", "40", "95"] which wont display the graph correctly. Is there anybody that has encountered something like this before and what can I do to make my values convert into a number array. Thanks for any help
