how can I check what is being return to rating.js from ajax.rate.item.php below?
rating.js
Code:
if(window!=top)top.location=location.href;
function RateItem(varItemId, varRating)

is there a way to assign an event to a file input so that when a user selects a file to upload the event is triggered and i can check out the file extension? The reason why is simple, i want to perform different actions depending on the type of the file.
View 2 Replies View RelatedI have a form with three Input File form objects in which the user can add image files. But I am worried about the problems these controls can lead, because to check the file size the server needs to receive the entire file, so serious problems may happen, for example:
1. Malicious user trying to collapse the website sending big files.
2. Users that have not seen the warning “Maximum size: 100 KB� for each image, and try to send three image files consisting in 1,5 MB each one. These users will have a bad experience waiting one hour or more to upload the images, and after that receive an alert saying “Oooops! Your image files are too big.� And also, web server will waste an important amount of resources. The same case with 100 users at the same time can be a nightmare!
I have been searching a way to check the file size on client side without having to force user to install anything, but I think that there isn’ t nothing to do with javascript. But I found an interesting PHP article that explains a way to do it with this server side language. The technique consists in:
“A hidden field (measured in bytes) that precede the file input field, and its value is the maximum filesize accepted. This is an advisory to the browser, PHP also checks it. This form element should always be used as it saves users the trouble of waiting for a big file being transferred only to find that it was too big and the transfer failed. Code:
I am having troubles finding a way to use JavaScript to see if a file exists before an ASP file upload script runs. Is there an Exists check for JavaScript? I thought I found an ObjectName.Exists but doing this did not work.

View 12 Replies View RelatedWhen i select a file (through html file control) from local machine, before uploading i want to check if the selected file exist(because,after selecting and before submitting the form,user may change the name/delete the file from the source). so after selecting the file, i need to check the same file exist as it is using javascript/ajax. Back end is JSP.Eg: Am selecting abc.jpg from my system and changing the file name form the source as abcd.jpg, now abc.jpg does not exist. But i want to check if exist.

I sell didjeridoos and handdrums.
I was hoping to create small html program for each drum, somthing like this....
<script>
thisdrum=new Image()
thisdrum src=drum001.gif
price=100
rim=12
height=24
</script>
<script src=createpage.js>
</script>
and saved as drum000 to drum999
Now I need a function included in the creatpage.js, that checks if a file exists,(eg drum000.html) if it does, go there, if it doesn't, try drum001.html
any suggestions on how I could go about it?

This is probably going to show how new I am to jQueryI have a form with an input text field for entering a URL. The user will most likely paste a URL and I want to automatically verify it's status once the user leaves the field. Basically just make sure the page loads ok.I've found dozens of topics that are close to this, but my lack of jQuery skills is hindering me from adapting any of them properly.

is this ok or is there a better way?
actually there's no error in the code only that is only made to check for one input field and my form has 3 image upload fields, the original is:
<form enctype="multipart/form-data" action="action.php" method="post" onSubmit="if(!this.img1.value.match(/.jpg$/i)){alert('Must be JPG file');return false};return val(this)">
<input type="file" name="img1">

Is there a way by which I can validate in javascript whether the file I'm trying to upload is an existant one(i.e., one which is present in my local folder).
View 1 Replies View RelatedI am using jquery.validate.js for my validation. I need to validate some dynamic input fields. By using class now I am able to validate that. Here my problem is to validate for the file extension.
For static files I use as
file: {
required:true,

How to write the accept validation for dynamically generated input fields. Below is my input field where the ID and name will change for every input field.

View 10 Replies View RelatedHere 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 have a list of checkboxes, the number of checkboxes is dynamic. All the checkboxes have same name. i am trying to get the length of selected checkboxes.
<input type=checkbox name=name1 value=1>
<input type=checkbox name=name1 value=2>
........ get dynamically.
when i try to get the length in javascript like document.form.name1.length, it works fine if number of checkboxes selected are more than 1, but not for 1.
