Prevent A Javascript Function From Executing Twice
Jul 23, 2005
I have a select dropdown and 5 text fields. based on the option
selected (which are the units - cm/mm/inches/ft/yard etc), i change
the values in the text fields using javascript to the corresponding
units.
my problem is that when the options are selected very quickly(for eg
using the keyboard's up/down keys) then quickly, the text field values
lose their connection with the select box and the values become
illegal.
I suspect that the javascript function is being called even before the
earlier execution has not terminated. I tried using a global variable and using it as a lock, but still no success.
Is there some way from preventing the JavaScript code in a document loaded into an iframe from executing? I don't have access to the pages being loaded into the i-frame so I can't modify then. They are being loaded from a server.
I'm using mooflow code on my website, problem is that it shows images on top of one another, before script arranges them to row. This only happens with explorer.
You can see example of the images popping up (and scroll bar flashing on the side of the page), when this page is loading on explorer, [URL]
Could there be some solution for the explorer so it wouldn't load images before executing the script? Other browsers work better with the loading order.
I am using an ASP.NET AJAX control (ValidatorCallout) that requires client-side validation to work with a custom validator I added. This is an example of some code that works:
ClientValidationFunction="CheckPrime" ControlToValidate="PartNumberText" ErrorMessage="b><br />A Part Number is required."></asp:CustomValidator> <script language="JavaScript"> <!-- function CheckPrime(sender, args) { var iPrime = parseInt(args.Value); var iSqrt = parseInt(Math.sqrt(iPrime));
for (var iLoop=2; iLoop<=iSqrt; iLoop++) if (iPrime % iLoop == 0) { args.IsValid = false; return; }
args.IsValid = true; }
This is code I borrowed from another site to test this method - and it works. My problem is that I need the JS to execute a VB function in my project and I don't know how to do that. I want to do something like:
function CheckValue(sender, args) { var sPartnumber = String(args.Value); if FindExistingPN(sPartNumber) { args.IsValid = false; return; } args.IsValid = true; }
....where FindExistingPN is a funciton in my VB class. I have seen some other posts about this, but none of them really gave me any sample code that I could run. As I mentioned earlier, my JS skills are lacking, so I am unable to create this myself.
I'm trying to execute a bat file on the server in javascript. The javascript sits on the server as well. I'm currently using:
document.location.href='testme.bat'
However the only thing it does is just opens up the bat file and shows my bat code in the browser. How can I execute the batch file instead of opening it and viewing it in the browser?
For some god-forsaken reason (which I can't find out either) MSIE stopped executing any JavaScripts. In any page which contains JavaScript code, that code won't be executed. There are no error messages, no warnings, nothing. It simply does'nt work. I'm pretty sure this could be caused by some stupid installation of another program that messed up some IE settings.
Security settings for IE are all lowered down. Everything is activated (Scripts, ActiveX, automatic download of anything, anytime)... so we ran out of ideas of what could be the problem. And yes, we have also tried to reinstall IE.
The only clue we have is that a local Administrator user can change IT security settings for himself and (go figure) things work fine! The problem occurs with users that have limted access to the computer and I am pretty sure this shouldn't happen. If you are wondering... yes... the local administrator has already tried to change the settings for limited user account..
What I am trying to do is dynamically update an image and image map on a page. I'd like the update to happen as quickly as possible and be done without refreshing the page. The catch is that the image map uses the wz_tooltip.js (http://www.walterzorn.com/tooltip/tooltip_e.htm) library to display a JavaScript tooltip containing detailed information about different areas of the image. So, when I pass the required <script> tags via .innerHTML, the browser treats it as text and does not interpret the JavaScript and execute the code.
Basically, I have a page that I load with 10 input fields. If users have JS enabled I want to hide 5 of these fields so as to reduce clutter. If the user needs these extra fields an "Add" button can be used to display the hidden fields one by one.
Once the fields a filled in the user submits them for validation and if there are any error They can "Go back" to make some changes. The whole process works great in FF & Opera but IE lets me down because if you use the Browser "Back" button the Javavscript gets executed even though it should be loaded out of cache.
I need to execute a javascript function on a page on a site. The link of a button is javascript:executefunction(2). However, I need to execute the function javascript:executefunction(1). Is there a way to do this by typing it into the internet explorer address bar (like the view-source:address thing)? Or is there a program that can accomplish this? I need to do this to test how it would execute the command differently. I have no access to the server (it is not my server/site) and don't have to option of download all the files to my computer (too many external css and js files).
i've been trying to make an animated fly/slide-out menu and am just trying to get the basic mechanics down. long story short i'm just starting with a simple mouseover/out setup to get things going.currently (as seen in the code below) i have a div which should simply move down 30px from its starting point on mouseover and return to its starting point on mouseout. this works perfectly the first time the mouse enters and leaves the div but nothing happens the next time the mouse enters the div unless the page is refreshed.
I'm trying to run this script on Firefox. I'm copying and pasting the whole thing in here just to be safe, but I'm mostly concerned with getting the findLegendary function to call catchPok(). The script executes fine, goes into the battle, but then...does nothing.It runs the catchPok function if I manually click and deselect the "Find Legendary" window option, so alternately, if somebody knows how to make the program automatically click the element at that point to stop repeating the function (maybe?) and it works, I'd be just as happy with that. My best guess is that the autoContinue function might be interfering somehow, since it runs that portion of the code with the manual findLegendary shutoff, but to be honest I'm pretty clueless.
What I want it to do is run the catch function through, catch the game pixel, and then go back to repeating. I don't care how this is accomplished as long as it can feasibly loop. The game rules allow botting, so this isn't against any site rules, either.
Following is my problem def: Load a HTML page and set the form fields on that page and submit it using javascript. I tried following code: I wrote a html file with following code in it.
I have an application that navigates through the links in a document, most of which are "javascript:doThisFunction(args)" type of links. Using DOM navigation I can find the reference to the javascript function and store it as a String variable, but is there a way to execute the function? Currently the only way I know how to do it is in a series of if/else statements as in:
if (link=="doThisFunction(args)") doThisFunction(args); else if (link=="doThatFunction(moreArgs)") doThatFunction(moreArgs); ... etc.
Need the closeAll() function to execute before the div's slidedown.All divs are initially hidden, just making a check that if one isopen, it must close before any new div runs.Can someone help point me in the right direction?Here is what I have so far.
function closeAll() { $(".div1").slideUp('slow'); $(".div2").slideUp('slow');
I have a hidden div containing a table. When the user enters a number into a text field and presses submit, the div containing the table appears. That's what is suppose to happen anyway. I am using an onclick function within the submit button to change the css display from none to block. The javascript is not executing.
Code: How many devices do you want to register? <input type="text" name="rows" id="rows" size="2" > <input type="submit" name="submit" value="Enter" onclick="showRows();">
The javascript is Code: function showRows() { var numRows = parseInt(document.getElementById('rows').innerHTML); if(numRows != "") { document.getElementById('Table').style.display = 'block'; } else { document.getElementById('Table').style.display = 'none'; }} Am I going about this the right way?
I have this line in my code: echo '<a href="" onClick="yesnolist()">Free Chat</a>';
Then at the top I have: <? php //have some php here ?> <div class="innerContainer"> <head> <script type="text/JavaScript"> function yesnolist(val) { alert("lakjsd"); var e = confirm('Do you want to send a free chat request?'); if (e == true){ window.location.href = "[URL]"; window.location [URL]; return true; }else return false; } </script> </head> <span class="headings2">CONTACTS</span> //and more code after this echo '<a href="" onClick="yesnolist()">Free Chat</a>'; Why is it not doing my onClick()?
I'm an experienced programmer (c, perl , python, bash) but absolutely newcomer with Javascript. The code I'm experimenting with is shown below. What I'm trying to do at this point is define a function in a script section in the head of my html page, then call that function in the onclick action of a form button. Sounds trivially simple, but for some reason it isn't doing what I expect. The eventual result will be that the Javascript will launch a Silverlight video player using the values supplied by the end user, but for now I just want to get the basic buttons to work.
<code> <html> <head> <title>Silverlight player</title> <script type="text/javascript"> var vProto; var vServer; var vStream;
function showMe() { alert("In the function"); vProto = document.getElementById('proto').value; vServer = document.getElementById('server').value; vStream = document.getElementById('stream').value; return false; }
function alertMe() { alert(document.getElementById('server').value); return false; } .....
Is there a function in javascript the same as PHP's exit(). I have: <script> ****EXIT OR EQUIVILENT IN JAVASCRIPT***** </script> <a id="java" style="color:#FFFFFF; ">Enable javascript to view my website</a> This tells me if javascript is on or off.
I've been having trouble with a seemingly simple function...I have a form where 3 of 5 field values are generated by a script tied in with Google Search (like a business address). The user is prompted to enter their business license #, and as soon as the input field has val().length == 9 characters, I want to execute an ajax call among some other functions... The problem is the function works when there are 9 characters in the field, but only after I generate a new and different set of values for the generated fields (i.e. the first generated values, coupled with those 9 characters isn't enough to set off the function, although when i use a second set of generated values, the function kicks in). Here's the applicable code...although there's a lot more to the picture...
I would like to execute functions based on the value of a form. This is the code I have. <input type="text" id="posttitle" value="Title" onblur="if(this.value.length == 0) this.value='Title';" onfocus="if(this.value == 'Title') this.value='';"> Now let's say I want to execute the function "myFunction()" onblur if that same condition is met, so not only will it recreate the value "Title" but it will also execute a function afterwards. How can I achieve this? I assumed I'd do something like... onblur="if(this.value.length == 0) this.value='Title' myFunction();" But that did not work.
I have a strange issue currently within my event.state I have a function that I would like to execute. So you can say that event.state = function(). How I now execute this function that is stored in event.state?
I made a function call on the form onLoad event and it is ignored in firefox. I place an alert box just b4 the fucntion and it is called correctly by the browser but it stops when it enters the fucntion. This work as it is intended in IE. How do I make a fucntion call in Firefox?
