Hi

Hi


I am trying to check for invalid characters in two text areas in a form as shown below:

1.
<textarea type='text' rows="10" cols="100" name="comment" maxlength="1000" id='comment' required /></textarea>

2.


<textarea type='text' rows="10" cols="100" name="comment2" maxlength="1000" required id='comment2' /></textarea>


I am checking for invalid characters via this jquery function:


<script>
$(document).ready(function Val(){

if (/[*?]/.test($('textarea').val()) {
// do something
alert("Invalid characters found and not allowed.Please check");
}

})});
</script>


My question is how do I call the above function ?

Hi

I am trying to pass data, namely through query strings, using jquery and ajax between two php files:

In ecovib2d_adriant.php (calling program):-jquery in function changePic



$(document).ready(function(){

$.(“Graphic_select”).change(function{
$.post(“watermark.php?Pic=“ + picname + “&Person=“ + personname);
$.send();
});

};


In watermark.php: I get picname and personname via the query string and then put a watermark on the image and then construct a query string using ajax to pass back to ecovib2d_adriant.php the resulting image file:


$url = ‘https://www.ecovib2d.com.au/ECOVIB2D/MYART/ecovib2d_adriant.php’;



<script>

$.ajax({

url: $url,
data:{“?image=“ + $imagew},
type:”POST”
});
</script>

Can anyone please help? ($imagew is the watermarked image file)
