Testing Data Types Accross Multiple Function Parameters?
Aug 20, 2010
So I have a function, and in that function there are two paramaters: index and newLocation. Each of these parameters can initially either be an integer or a string: The string can only be the values of "first" or "last". I can do a long set of code for both parameters, but I was wondering if there was a way to iterate through the parameters to make the code more compact and reusable.
if(parseInt(index, 10) == "NaN")
{
if(index == "first")
{
//The first index of the array
index = 0;
I'm probably missing something simple here. I have this function called display:
function display(name3,office3,officePH3,mobile3,email3) { document.getElementById('viewer').src=('Location_Files/')+(office3)+('.htm') }
It's supposed to take 5 values and do various things with them. When I only had one parameter it worked fine, it took an office number which was the value of a listbox option and turned it into a path and then pointed an iframe to that path. Then I changed it so the value of the listbox option was 5 parameters separated by commas. Here's the listbox now:
You can see display is executed as "display(this.value)" so in theory it should take "test name,1656,phone,NONE,email" as its parameters and it should accept 1656 as the "office3" parameter. For some reason it's not working out that way, the function executes and the iframe changes but I get an unable to display webpage message like the path is broken. Can anyone see what I'm doing wrong?
I have written the following code (quite meaningless. Just to check why setTimeout is not working in a similar real-life code) to enable the user to input a given time interval (hh:mm:ss) when a p is clicked, and then alerting the user with the time entered in the seconds portion one second after the div is clicked. But it is not working. I think the setTimeout is the culprit, the way I am passing parameters to the function inside it, but don't know where exactly am I erring.
Can I find multiple objects in one call? For example, I have ahold of a TD object that has in it input and select objects. I want to addClass to both the input and select objects therein? Something like ".find('input || select')"? Otherwise I guess I could just do multiple calls similar to:
//First find all of the required elements indicated by the red * $( "span[class=redEmphasis]").each(
I'm pretty new to jQuery and I'm using $.getJSON to submit some data to a PHP script which either returns 5 sets of json-formatted data or data to indicate an error condition (i.e., no data available) from the PHP database query. The callback routine handles the 5 sets of json-formatted data just fine (using $.each...) but I'm having trouble testing for either just a string with 'null' in it or a json-formatted data return of [{"error":"null"}].
My callback code for the second approach looks like this: function handle_stores(data) { if (data.error == "null") ..... But this test does not execute the following code for the 'true' condition, i.e., data.error == "null" never evaluates to 'true'.
I had a rethink about my problem discussed in this [URL] thread, where the function won't run properly a second time if the page hasn't been reloaded. That one appears not to have a solution, and I was thinking that a reasonable plan B is the following:
a) test if the function has already been run since the page was loaded
b) if not, run the function
c) if it has, reload the page with the onClick, then run the function automatically on reloading.
the problem I envisage is will the page "remember" to run the function once it has been reloaded?Of course, it would be simpler to do it running the function automatically once the page loads, then just reloading if the test comes back that the function has been run already, but that wouldn't work for the first time you visit the page - it would start running straight away, whereas I want it to wait for that first click. Here's the page [URL] I'm working on, if you want to have a look.
I have an HTML page which loads another page inside an IFrame. Each of the two pages has its own javascript code.
I would like to be able to define one global variable which will be accessed from functions in both scripts. The variable must be single. That means that if a script in one of the pages changes it, the change will be seen by the scripts in the other page.
Ok I am pretty sure Javascript is the only way to do this I need to pass more than one parameter from a form to a url For example:
I need this output
Code: http://mywebsite.com/index.php?price_min=10&price_max=20&sort=featured I would have no problem if I only needed Code: http://mywebsite.com/index.php?price=10 Code: <form method="get" action="http://mywebsite.com/index.php"
I have the below function and I keep getting the error Lid is not defined.
<script type="text/javascript"> function loadTips(file,ID,File,id){ alert(file); alert(ID);
[Code]....
So my alert Lid comes up with txtHintLees, so it is working up until the alert. Which leads me to believe that maybe it doesn't like being wrapped in "", without "" though firebug halts the process. I tried wrapping it in {} e.g. {loadXMLDocRefresh(File,id)} but that wasn't liked either. I'll stop my list of things I tried that don't work now.
Is there a way to send multiple search paramaters using the jQuery UI 1.8.1 Autocomplete feature? Currently, I am able to send only the text entered in the text box which automatically maps to the "term" querystring paramater. I need to send couple of additional parameters to my server side code for filtering the search. Is this possible?
Hi all.Am new to this forum so cut me some slack if I don't articulate my problem with utmost clarity.My problem is that I have a javascript function such as:
function modReg(x,y) { <!-- var answer = confirm ("Do you really want to deregister user" +x+"?") if (answer) { document.leo["id"].value=x;
[Code]...
Now, leo is a hidden form with the 2 fields namely "id and "two".Viewing source, I see that the parameters I need are well acquired by the function.In next page, I haven't been successful at retrieving the passed parameters.
JQuery seems to be giving an error when trying to pass an alphanumeric parameter like so:
[Code]...
when the above method is called, the error callback is called. However when I change the eventID parameter to a purely numeric value, it works fine and the success callback is called. I would like to pass an alphanumeric value to a server method and this doesnt seem to work.
Selecting elements using multiple parameters like here: $('descendant', 'ancestor').text(); seems to be way more popular than css-like syntax: $('ancestor descendant').text(); Do those two differ in performance, or is it just about being intuitive to particular people?
I have added an event listener to a LI item in the DOM:
liNode.addEventListener("mouseover", mouseOn, true); The mouseOn function: function mouseOn(e) { // Test for IE or Firefox var e = (!e)?window.event:e; var yPos;
[Code]...
I would like to pass in another parameter to the mouseOn function in addition to the event that is passed in automatically. Is there a way to do this?
I am making a function that executes code as AJAX readyState's are returned. If readyState = 3 then I running code through eval but I want to be able to run functions with parameters, within the parameter that is evetually executed by the eval
Heres abit of pseudo code of what I am talking about
function receiveRequest(whileLoading, whenDone) { // AJAX stuff... blah... blah... blah... if request is being processed: eval(whileLoading) if request is done: eval(whenDone)
[Code]...
I haven't used Javascript in agggeeesss and I can barely remember anything anymore - PHP <3
I keep getting a runtime error stating that this document.adddealer.dealertoadd.value = dealer; is null or not an object. I've rewritten the Function everyway I could think of, and couldn't find any thread examples of my problem.
Here is my Function;
<Script language="JavaScript"> <!--//hide function AddDealer(dealer) { document.adddealer.dealertoadd.value = dealer; document.adddealer.submit();
} //--> </script>
This calls the Function;
<input type="button" value="Make This My Dealer" name="button">
When the code breaks and I bring up Microsoft Debugger it shows a value in the parameter.
I have a problem with a function i created. I want an image to move from a to b and then start from a again. Without parameters this works really fine, but now that I have got more images I use parameters but I have no clue how to call the funtion again.
[Code]...
I tried to replace show(100,flo) with show(100,flo(zahl,r_g)) but then the divs only move from a to b but even will not come back to a again. I think the solution should be pretty simple but i cant figure it out.
