I'm having some weird problem with evaluating the continue statement.
Within a for loop I'm trying to evaluate a string (generated somewhere
earlier) which basically has the continue statement in it. IE6 seems to
have major problems with that as it generates an error "Can't have
'continue' outside of loop". Does anyone know why and/or have a
workaround? I haven't tried any other browser since this one is the
only one available (company policy).
I have included some code to reproduce this behaviour. The first and
second if statements of the testeval function behave as expected. The
third one however produces the mentionned error. Code:
I have this below which causes an alert after 10 seconds. How would I keep the alert going every 10 seconds after?
<script type="text/javascript"> //If the time is less than 10, //you will get a "Good morning" greeting. //Otherwise you will get a "Good day" greeting.
There are several forms on this page and I have absolutely no control over them. The page is provided by a 3rd party and all we can do is add javascript.
The form is a google checkout. I need to halt submission (preventDefault) do some stuff and continue the submittion of that form.
I have a page with three items that I want the user to agree to (a beta signup agreement).I want them to have to check off all three boxes before the "continue" button becomes active. I've searched and searched and found a few tutorials, but they only seem to get me halfway and then drop me off a cliff.I don't need this to be a submit form or anything, just click the three boxes and then you can hit the "continue" button.
Below is some very basic html/javascript that asks for a user to enter a number in an input text box and then a button is pressed it writes out a line that number of times. It works, but when run in firefox the pages always seems to continue to load...that is, the cursor is continuously that when a page is loading (an arrow with a little circle) and the status bar in the bottom right hand corner seems to be always be at zero. It seems to be something in the for loop as when this is take out it works. Seems to work in IE however?Is this a FireFox thing or am I not terminating the loop properly?
Is there another JS function that I can use to force a time delay without having the code continue to run? I'm using the setTimeout() function but the call to this function doesn't stop the code flow. I need to stop the code flow while waiting. I guess I need a Sleep() type of JS function.What I'm trying to do is display some blank text on the screen using a for loop (I'm using <BR> to give the appearance of "opening up" a vertical window section in the browser) and I need this 'text' to complete before allowing the following code in the function to execute. The following code will display a Table with rows of data. I'm trying to use a timing function to give a visual impression of a window opening up just before the data displays.
given that I have a js file included which is written programatically and I can't change it. I would like to know how to do the following using something other than the deprecated eval().
whats in the js file var numArrays=something; var data0 = new Array(); data0.name="name"; data0.data="some data"; var data1 = new Array(); data1.name="another name"; data1.data="some more data"; etc .... function getData(arrayName) { for ( var i=0;i<numArrays:i++) { var el=eval('data'+i); if (arrayName = = el.name) doSomething(el.data); }}
var fns = ['orde', 'no', 'kml', 'snf', 'td', 'ty', 'tn', ...up to 21 elms...]; var snv = new Array();
var vals = new Array(); for (i = 0; i < N; i++) { for (j = 0; j < fns.length; j++) vals[j] = some value; snv[i] = new makeData(vals); }
function makeData(vals) { for (k = 0; k < vals.length; k++) //the following line doesn't work eval("this."+fns[k]+"="+vals[k]); //neither this one this.eval(fns[k]) = vals[k]); }
how can i make it without writing it the long way:
I've made a funny program using eval()...it will let the person(on the page) to write javascript and have it compile(if thats the right word for it)! its quite cool, i dont know how handy it might be, but here it is none the less...
On my form I have 3 submit buttons which handle different things.I am looking for a way to stop or continue form execution with a confirm box on the third submit button and the third only.I can't use onsubmit because that will trigger on all three buttons.
I'm trying to use Javascript to have an array of images that load randomly AND work in a slideshow manner so change every 3 seconds (in a logical order). The code I have below presents a random image but how do I get them to continue from the random image and change to the next every 3 seconds?
I'm running some javascript over a server side generated web page and have multiple generated empty select statements, that I want to populate when the page is loaded. As HTML doesn't do arrays each select is individually named withe MySelecti where i is an incremental from 1. I know all my variables are correct (i, OptionsCount) and my arrays of MyValues and MyDescription's exist for multiple enteries and if I bring out an example of what I thought each line would eval too( say document.MyForm.MySelect1.options[1]=new Option('Value1','Description1') the line works fine, for the life of me (i'm sure I'm missing something obvious) the eval line won't eval..
This works perfectly fine for me, but this is a web-app that will be exposed to public users, and I obviously don't want them being able to eval anything if i can help it.
i came up with the following, to help me test the syntax of functions while i'm writing them. i've only been using it for a day or two, but so far, it's been really handy.
I have a script that will loop through all the INPUT elements of a form; if the input is a submit it will disable the submit (or enable the submit, depending upon what is passed to the function.) I hate using eval() - I avoid it whenever I can! Is there a better way to dynamically process the ".disabled = 'true'/'false';" portion?
Code: var tabs = new Control.Tabs('menu'); var pattern = 'tab='; var nStr = location.href; if(nStr.match(new RegExp (pattern,'gi'))){ var id = nStr.split(pattern);
[Code]...
It searches for the query string 'tabs=' and then splits the result to get the id of the tab. Then it uses this to set the active tab. If the url doesn't include the query string it set the tab to the first one.
The code works but it uses Eval to convert the id string (id[1]) to a variable and I was wondering if there was an alternative.
