I am using ASP to dynamically generate a series of forms. When the
page is loaded, everything appears to be correct, except that the
first form generated fails with a "FormName is Null or not an Object"
error. Each subsuquent form created by the code after that works
perfectly. Why is it that the first form, generated with exactly the
same block of code, fails? Code:
What I'm trying to do here is to create an editing form based upon the field descriptions extracted from a database, and use jQuery (e.g., datepicker) to handle the input. So, using the datepicker example, I create an input item, make it a 'text' type, give it a name and an id, and then use $('#'+textfld.id).datepicker({ ... }) to set it up. This is NOT done at $document.ready time, but while running the form's JavaScript, so I don't know if that's the problem or not; I can't see how to use $document.ready here due to the dynamic nature of each field.
AFAICT, what should happen here is that a jQuery datepicker should be created and associated with the text field - but nothing at all is happening.
I have a form with a number of <select> fields, some of which require additional fields to be displayed/enabled depending on which <option> is chosen. For example, in the following code, I'd like a <textarea> field to be displayed if users choose the 'Other' option:
<label for="venue_type"><p>What type of venue do you require?</p></label>
<select name="venue_type" id="venue_type">
<option value="null">--Please choose--</option>
<option value="Meeting/Training/Seminar room">Meeting / training / seminar room</option>
<option value="Computer Suite">Computer Suite</option>
<option value="Examination room">Examination room</option>
<option value="Lecture theatre / auditorium">Lecture theatre / auditorium</option>
<option value="Other">Other type of venue</option>
</select>
I'm guessing that it's possible to do this using onchange, but am not too great with Javascript .
Is there a tutorial on dynamic SID generation?

View 1 Replies View RelatedI'd like some help trying to generate input fields on the fly. What I
have on an HTML page is a single text input field labelled #1, e.g. #1
<input type="text">. Next to the field is a button that, on click, I'd
like to automatically generate a second text input field below the
first, labelled #2. Everytime the button is clicked, another field is
created with an incremented label.
I explored iframes, but these text fields will be part of a larger
form that has to be passed together. I'd rather not use hidden text
fields because I don't want to hardcode a limit to the number of
fields available. Please point me in the right direction, or let me
know if this isn't possible.
I have to do a project, the requirements i have got are, same link on multiple pages should lead to a single page on client's site, but the page should be different for each link clicked.
What i understand from this is, we will send parameters with each link to a JS or php file and then generate a dynamic page each time, but i am not clear how many files we need to call and what will be the sequence. I want to implement this in JS and php.
how to implement it with JS and PHP if we send parameters with the url and if we don't send any parameters.
I've been working on a redesign of our site at ExperiencePlus for some time now, and long ago chose CBE menu 9 over the other menu technologies out there because of its browser independance. Problem is, as you can see, we have a pretty large site; load-times for the menus and associated scripts are approaching prohibitive. So I'm trying to speed things up.
You can see the results of some simplification here - still about the same speed by my guesstimates.
So, my question is twofold, I guess. First, Mike, do you have any ideas about how long it will take X menu 4 to reach maturity? No pressure ;^) If it were ready now, I'd just drop CBE in favor of X.
Second question: How much performance improvement can I expect from removing unnecessary code (sliding, for example) from the CBE core files? I haven't played with that stuff at all, except to read it now & then when looking for solutions to problems. Does anyone have a similarly large implementation of CBE menu9 that runs faster, so that perhaps they could share their experience?
One final thing: I'm planning to eventually shove all this into a PHP document that will auto-generate chunks of the menu from database queries, especially around the tour & country listings and our "Resource Room." (X menu 4 looks like it would be vastly superior for that purpose, since it's so lean.) I'm interested in hearing from anybody who's tried to do something like this, whether they succeeded or not.
There's a feature I want to implement, but don't really know how to code. The intention is to use jQuery to convert words with a certain class attribute into Wikipedia links.
An example to make things clearer:
PLAIN TEXT: There is a <span class="wiki">penguin</span> there.
EXPECTED RESULT: There is a <a href [url] there.
Hence the code would have to grab the string of words inside the tag and place them inside a href with the first part of the link already attached to it. Doesn't seem too complicated, but I wasn't able to do it.
I have been trying to use the code below (created by Patrick Haney and improved by enraged) as a basis, but no deal. This code subistitutes words for code, but it searches for specific words.
If anybody knows a script like that, modify the code below,
I have a small number of functions on an object and for every function I wish to make a different function that calls the original where the this can be passed as a parameter. I am making a library and this is a convenience method for people who don't know about call/apply.
Currently (one of) my function looks like this:
function _find(){
return find.apply(arguments[0],Array.prototype.slice.call(arguments,1));
}
However since my functions are in a object I was wondering if I could make a new array dynamically?
var func = {'find':find}, func_new={}; //this is just an example I don't have this part in my code
for(var attr in func)
func_new[attr] = Function('return '+attr+'.apply(arguments[0],Array.prototype.slice.call(arguments,1));');
One of the links adds a button to the form dynamically (and also removes it).I give the button an onclick event handler that also removes it from the page (basically just setting its parent.innerHTML='')A third link submits the form using a function (for validation perhaps).The third link submits the form successfully, EXCEPT when I have removed the newly created button by clicking on it. In this case the form.submit() is simply ignored although the function is still executed.This is essentially the problem I have: The link fails to submit after using the button to remove itself.If I hide the button using the first link and/or change the button's onclick to do nothing then I can still click it and the form submit succeeds.Here is the test code:
Code:

I have created a simple form for uploading text files.You can see two versions of this it at: http:[url]....The form created with static HTML, works fine in current versions of the major browsers.However the dynamic form, fails (only) in IE.It fails because IE does not send the file at all when the form is submitted.
View 7 Replies View RelatedI am missing something *super simple* it seems: I have a <form...> like so:
HTML Code:
<form id="fromPreview2commitForm" action="[thisurl]" method="post">
..on a page with JS like so:
Code:
function userBackingOutFromPreviewing() {
document.forms["fromPreview2commitForm"].submit();
}
and an anchor like so:
HTML Code:
<a href="javascript:void(0);" onClick="userBackingOutFromPreviewing()">here</a>
but I am getting this error in FF3/Mac: document.forms.fromPreview2commitForm.submit is not a function Why?I just want the anchor (when ciicked) to submit the form.I have been over several examples I found while googling.. and I follow them.. but still getting this error.
I've got some strange behavior with validation. I'm loading up a form to allow editing of an existing database entry. If I make my changes to the fields, enter in the required "revision comments" and submit, the page does NOT post, it seems to only refresh and empty out all the entries in each of the fields. Now, on the other hand if I open the form to make changes to a database entry and immediately press "Submit" without filling in the revision comments field, it fails validation and tells me to enter comments. Now if I fill in comments to satisfy all the requirements and press submit, it posts and I get my "Successful Entry" confirmation prompt. I think I've narrowed it down to the remote: part of my jQuery. I eliminated by trial-and-error the other pieces of the jQuery code and it seems that when I remove the remote: it does not experience this strange behviour.

I am having a problem with the last results. I can't seem to be able to
get the input2A and input3A to appear. I don't seem to have a problem
with the show and hide after a number is entered and submitted. If
anyone can answer my problem I will be greatly appreciated with a

anyone been able to answer it yet. Code:
I have a problem where if a form submission (set up to submit via AJAX) fails validation, the next time the form is submitted, it doubles the number of post requests - which is definitely not what I want to happen. I'm using the jQuery ValidationEngine plugin to submit forms and bind validation messages to my fields. This is my code below. I think my problem is that I need to unbind from the validationEngine plugin when the form fails, but I can't figure out how to do this.

I am making a call to a php file which right at this minute has no validation, all validation is been done by the jquery form plugin. the validation (xss prevention soon to be implemented) in the thanks fails I want to stop the processing of the form i.e. stop the return of success.

All the numbers should match. It's not working right in any version of IE I test it in (6, 7 and 8). I'm also using jQuery, fyi.When you click the button to stop the numbers, I'm setting a variable named winner to a number (3, 4 or 5). Right now, I have it set to 5. This number determines how many of the slots match:[code]I'm then generating a random number (0-8) to base all the other numbers off of . Three numbers will always match, so I'm setting two more variables to match that random number.[code]Then I do some conditionals to check the value of winner. If it's 4, I set the 4th number to random number, then generate a random number for the 5th spot while it doesn't equal randomnum. I do something similar if winner is set to 5.[code]The goto trigger sends the scroll to the specified index according to slotnum(1-5).I'm waiting to hear back from the plugin developer to see if it's something to do with that.However, I just want to make sure my logic in generating those numbers is sound. It works perfectly in FF, Opera and Chrome but (surprise!) not in any of the IEs (tested in 6, 7 and 8).

I am teaching myself javascript and in the course of my experimentation have run into this roadblock: I want to display a styled navigation bar with a button beneath it. When the button is clicked, an onclick event will be triggered and the response of the browser should be to print the word "test" right beneath the button. However, what actually happens is the page blanks out and the word 'test' appears in the upper left corner of the screen.

I'm working on a script that will produce multiple dynamic forms based on the results of an ajax request. The ajax request does a db query that will return 0 to x number of rows. For each row, a new serialized form is created. Since the forms do not exist at page load, I'm having problems getting the value of the form elements so that I can run other functions on them (update inputs and selects). I've stripped down everything so that I can show a basic example. In the example, how would I get the value of "#orderID"? The body contains a div (previousList) that has a list of items that when clicked will trigger the ajax query. It also has a div (line details) that will hold all of the forms that are generated.
<div id="lineDetails">
check it out </div>
<div id="previousFrm" class="ui-widget-header ui-state-highlight ui-corner-all">
<h3>Previous Returns/Cancels</h3>
<div id="previousList">
<ul class="previous" id="returnList">
<li id="1000997" class="names">1000997: 101853</li>
<li id="1000995" class="names">1000995: 101853</li> .....
But callingconsole.log("order line value is " + $("#orderID").val());
results in 'undefined'.
I have a site that has dynamically generated forms with multiple submit buttons. My forms are like this, created using PHP and inserts different user names on the same page:
[Code]....
The member name goes into the JavaScript to variable: member. The Problem: is when this JS tries to submit the form called "john" for example, it searches for a form called "member" instead and it fails. Is there any way to fix this? I'm sure there is a way to deal with this kind of issue but I don't know it yet.
I am using DW8 (I've read some comments about DW here, but its helping me to learn how to code beter), in creating a contact page I have the following
<body>
<script type="text/JavaScript">
<!--
function MM_jumpMenu(targ,selObj,restore){ //v3.0
eval(targ+".location='"+selObj.options[selObj.selectedIndex].value+"'");
if (restore) selObj.selectedIndex=0;
}
//-->
</script>
<form name="form1" id="form1">
<select name="contactType"
<option value="" selected="selected">Choose Type</option>
<option value="/pgs/generalquestion.htm">General Question</option>
<option value="/pgs/orderquestion.htm">Ordering Question</option>
<option value="/pgs/techquestion.htm">Technical Question</option>
</select>
</form>
</body>
The links (ie "/pgs/genuestion.htm") do send to the correct page. However, I would like the form to 'dynamically' appear under the list menu based upon which selection is made instead of directing to a new page. --- Each contact form would contain the same info ie. name, comment textarea etc., but the three different types (gen, order, tech) would be sent to separate emails ie gen@domain.com, order@domain.com... respectively.
