View 5 RepliesI am a php programmer and not a Javascript programmer and I am trying to help a friend out with his shopping cart. The original programmer (who wrote this years ago and is no longer around) has a button that looks up the quantities in the database for the submitted items, and then displays a prompt if you selected a quantity that is less than the minimum purchase amount.The issue is if the user enters a smaller amount than allowed and hits the enter key instead of the "Buy" button, it allows the order.how to use the current code to also check for an Enter key submission.I can handle the PHP and the db lookup for minimum quantities. Here is the page code and the Javascript code.
Code:
<a href="javascript:checkQuantity(document.form<?php echo $formCount; ?>,
<?php echo $row_rsProduct['lotQty']; ?>,
[code]....
I am trying to check the user enter time with current system. If user enter the time less than the current system time then I want to display the alert box. But the code is not working. Here is the code
<html>
<head>
<title>test</title>
<script type="text/javascript">
var d = new Date();
var curr_hour = d.getHours();
var curr_min = d.getMinutes();

The code below puts a link in mydiv when the page loads if myvar equals 1. Great till here, but if myvar changes its value and it does not equal 1 any more I have to reload the page in order not to see the link. What do I have to do to avoid that reload? what do I have to do to check myvar's value for changes constantly?

is there a JavaScript equivalent to the PHP isset() function? Basically, I just need to see if an array has already been created. If not, I'll create it. If so, I'll add to it. I tried something like...
if (!myArray) {
var myArray = new Array();
myArray[0] = someString;
n = 1;
} else {
myArray[n] = someString;
n++;
}
...but just got an error message that myArray was undefined. What's the "right" way to do this?
<input type="button" onClick="doSomething()">
When the user click HTML button, it will launch doSomething(). But I
want the user enter ENTER key, it will have same effect.
I am currently trying to check using javascript whether a php array contains a variable, and if it does then display a message.I have written the following code...
<?php
//php which sets users array to the results of the sql
$selectquery = "SELECT Username FROM User";
[code].....
i have captured the session value and displayed in a variable result.
suppose if i have result =0.then it does not display true.it still displays false.
how do i check whether result is empty or not.
function checkSession()
{
var result = <%=session.getAttribute("INTPERCENT")%>
alert(result);
if(result=="")
{
alert('false');
return false;
}
else
{
alert('true');
return true;
}
}
I need to change the code below so that it will check to see if there is a value for the model variable, its a select dropdown in a form. If there is no value then I don't want the var model to be included in the url part.
I also need to check to see if the var pics is checked (its a checkbox) if its checked then i want to include it, if its not checked then again I need to miss it our from the url part.
Code JavaScript:
I'm processing a form with numbered fields, but I don't know how many fields there are. Might be 1, might be 20. So I'm iterating through 1-20 and trying the following test:
for(i=1; i<=20; i++) {
if(typeof(eval('document.edit_orderitem_form.field_'+i+'.value')) != 'undefined') {
[doing stuff with the form field here]
}
}
The script quits on that line with "Undefined value" showing up in Safari's error console. I just can't figure out how to eval() the name of a field when it may or may not exist.
I would like to check the querystring to see if a variable exists.If groupid exists in the querystring and has ANY value then show a hidden div (#closedMsg). I do not care what the value of the groupid is I just want to verify that it has a value.If the url looks like this "www.somesite.com?groupid=" with no value for groupid, I do not want to show the hidden div.
View 2 Replies View RelatedThis is my first adventure into PHP/Ajax/MySql/Javascript and is pretty much my first web project. I've been trying to tackle this problem for a little over a week now. My main objective is that I want to display php content pages inside a div on the index page without refreshing the page (iframe style). I don't want to stop search engines indexing the individual pages so I need a mechanism to redirect to the index page so that the page is displayed properly. I'm not bothered if it takes them to the exact page and I'm redirecting them to the section of the site where they the page is kept.
I also want a mechanism to redirect if a second search engine link is clicked that belongs to the individual page (ie image links that belong to the same page). This is only a problem because the php session has already been opened and a php variable has been set by the first redirect. All the redirections are taken care of by PHP and I got the redirection of multiple instances working ok by setting and unsetting session variables. This PHP code is included on every content page.
But, when I added links to the index page and try to navigate between pages, it all goes pear-shaped.When the links are clicked it calls up the Javascript code, inside which a PHP variable is set (I dunno if this is the "done" thing, but I came across the solution somewhere on the Interweb). This is the first thing checked when the content pages are called up. If the variable isn't set, then it runs through the redirect options.
The problem is that after clicking the link when the page displays it always refreshes the index page which I don't want it to do and which is why I'm thinking it's the setting of the PHP variable inside the Javascript that's going wrong. (Also why this question ended up in this section). Is there any way of getting this going without passing the variable into the url (not that I'm against this option)? Index page code, PHP Code (before HTML)...
Code:
<?php
if(!isset($_SESSION))
{
session_start();
}
// set the session var to the index page url which I think remains until browser close
$_SESSION['pagecheck'] = "http://".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
// set the section var if it hasn't already been set by one of the content pages
if(isset($_SESSION['sectNum'])!= "undefined")
{
$_SESSION['sectNum'] = "0";
}
function getSection() .....
Additionally, are there any potential security threats that should be tackled (bearing in mind that I don't want to use cookies, I'm not against this either but decided if they are switched of it may become an issue, and I'm not going to be handling any sensitive information). I really don't want to use Iframes due to any javascript switching off related problems (yes there is a javascript testing function included in my full code!).
Here is the HTML: [URL] I'm trying to uncheck the selected radio button, then set the value to 1 (Yes), basically overwriting theinitialvalue to 1. I've looked at prop(), val(), and attr(), and just don't know where to start. Should I select $('#set_q157 input') or$('#set_q157 input:radio'), or each individual radio?
Do I need to each them, and check if its checked, then change its value, or is there a way to select all three inputs as just one radial button? It would also need to work if the input has not yet been checked.
I want a function that when you check on a check box another check box appears.

how to first have user enter a name in a search box. There are a bunch of divs with class 'thumbwrap'. Within each div is a span that will have a unique name and an img tag with a unique alt name.
I would like to take the 'name' entered in the search box and find the div that contains either the matching span name or matching img alt name (two different types of searches - could you show how to write both)
Once the div(s) are found, would like to select all the other divs and hide them, ie left with just the matching div showing.
I need a way to set everything back to showing as well.

View 1 Replies View RelatedI have a form that I built, and I replaced the submit button with an image.When you click the image, it calls the .submit() jQuery function and submits the form.Because I am not using the normal submit input button, hitting enter in most browsers won't submit the form.I think that users are used to this happening, so I would like to replicate this.Can I trigger the .submit() function when the enter button is hit?
View 2 Replies View RelatedI have a form with a bunch of selects and a single text input.Form data is sent via $.post whenever the inputs are changed, so a submit button isn't needed. The form does contain one regular button (using the button tag, not the input tag). The button shows a jQuery UI dialog when clicked.
If you press the enter key in the text field, the browser submits the form but it also acts like you clicked the button (the dialog appears). That makes no sense to me. Why is this happening and how can I stop it?I've already tried adding a few things to the form's submit handler, but they don't make a difference.
$('#filters').submit(function(event) {
event.preventDefault();
event.stopPropagation();
clearTimeout(window.refresh_timer);

In my application,there are several autocomplte field is available.When I type "pank" and then it list out the several matching in the autocomplete field and select one and then hit the enter then it submitted the entire form, which will cause the error message.

Ok, so I've built a member search using ajax to change the results each time a filter is changed. It works great, except one minor issue that I'm struggling with...I just can't specify dynamically in the parent file that linkclass$id opens linkclasscontent$id as I don't know of any way to pass that $id variable back over to the parent.
View 3 Replies View RelatedI want to bypass from one input field to other one by <enter> (<return>) key pressing instead of default behaviour (<tab> key pressing).But there was default form action on <enter> keydown event was performed. Remember that <enter> keydown event on form means default "Form submit" action. How to prevent default action, form submission, in time of <enter> keydown event processing?

I've just started using the jQuery Autocomplete plugin [URL]I get my completions from a serverside service. Currently I'm using the option selectFirst: false. When I'm using Enter without selecting from the completion list, this submits my form. This is fine, but the displayed completions stay visible after submit. How can I hide displayed completions when hitting Enter without selecting a entry? (As expected, displayed completion list disappear when selecting a entry and hit Enter or Tab)
