I am trying to link the javascript to my html file but it is giving me Unknown error String is not a function! Could somebody please tell me what is wrong!!!
Also I do not want the validation to take place on submission but on click, I mean every time I press tab. Is the following code correct?
function validate()
{
var name=document.forms[0].name.value();
var fac= document.forms[0].fac.value();
var erp= document.forms[0].erp.value();
var contact=document.forms[0].contact.value();
var studh=document.forms[0].studh.value();
var sc=document.forms[0].sc.value();
var reg=document.forms[0].reg.value();
}
Replace all:
.value();
to:
.value;
Because value is an attribute and not a function.
.value is an attribute, not a function. If there is Harshita Pathak in your name field, document.forms[0].name.value is a string "Harshita Pathak". You are trying to call "Harshita Pathak" as if it was a function when you append ().

I Tried this code to get multiple value in href but it does not work. any problem on this one ?

You are missing a + sign between a string and a value.
The error is between this two
document.getElementById('CUS_CODE_MX').value '&AGE='
Correct format
document.getElementById('CUS_CODE_MX').value + '&AGE='
Every time you join a value and a string, you need a + sign
Even if you are joining two strings
'Hello'+ 'World'
Pliss avoid long js as an inline atribute. I will recommend you call a function as the onclick attribute.
Hope this helps :)

It's better to use external script for that rather than inline format. And just add missing + to your code. Also, using variables would clean up the code.
function func() {
var CUS_CODE_MX = document.getElementById('CUS_CODE_MX').value;
var AGEID = document.getElementById('AGEID').value;
this.href = 'printsales.php?CUSTOMERID='+CUS_CODE_MX+'&AGE='+AGEID;
}

I have a variable var that contains a date "29/5/2017" in my page. Now i am trying to pass this variable to a function that is stored in a separate js file. My issue is when i debug the js i see a number 0,0028... The js believes that this is a number a makes a division. how can i prevent this and pass just the date?
the var in my aspx file is :
var mydates = '29/5/2017';
the function call in my aspx file
calldate(mydates);
the function in the js file
function calldate(mydates) {
alert(mydates);
}
you need to use double quotations to single quotations mark during init variable
var mydates = "29/5/2017".toSting();
and user .toString() function for canvart to string.
Thanks
Instead of passing date as string try to pass variable as Date datatype.
there might be chances that the variable getting changed before calling the function.
<pre>
var mydates = Date("29/5/2017");
</pre>
I have a very good regex function which call in here:
<input onkeyup="vimeo();">
But the problem is, when the user paste a link in to the input, he get this link:
//player.imeo.com/video/VIDEOID
You see? Missing "v" from vimeo and I can't pass on this problem.
If I delete the "/" character before of "v" I get repeated value, for example:
//player.player.player.player.player.player.player.player.vimeo.com/video/VIDEOID
My replace script looks like this:
var vimeo = function(){
var str2;
$('#url').keyup(function(){
str2 = $(this).val();
$(this).val(str2.replace(/(?:http:\/\/)?(?:www\.)?(?:vimeo\.com)\/(.+)/g, '\/\/player/\.\vimeo\.\com\/video/$1'));
});
};
How can I fix missing "v" without repeat any value?
Update:
Demo link is here:

The problem is your replacement string. You don't need to escape any characters. The second argument of the replace method takes a string, not another regular expression.
'\/\/player/\.\vimeo\.\com\/video/$1'
You can just do this:
'//player.vimeo.com/video/$1'
I am not sure why you are using a keyup event on your input as well as your url element, however.
I changed your function a bit and it works for me.
EDIT
Since you want to only use one field, you'll need to use onchange to format the url once the user is done editing. I've changed the function to reflect this change. Notice, you don't even need jQuery anymore.
var vimeo = function(elem) {
var str2 = elem.value;
elem.value = str2.replace(/(?:http:\/\/)?(?:www\.)?(?:vimeo\.com)\/(.+)/g, '//player.vimeo.com/video/$1');
};
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.0/jquery.min.js"></script>
<input onchange="vimeo(this);">
I got 6 "textboxex" and an Array with them.
<input id="slot0" type="text" /> id from 0 to 5, also Array named "slotarray". I want arrray and textboxes to be bound slotarray[0] with input id="slot0" etc.
First i needed function that will find first empty field in array (no matter if corresponding textbox is empty - but should) and put there string (short string - shortcode like "abc" or "sp1").
This function also need to populate bound textbox with long string.
If slotarray[2] == 'abc' then with the same number in ID (here be id="slot2") need to contain long string like "Abrasive Brilliant Conexant".
Here what i got
click to populate
and then function
function populate(shortstring,longstring) {
for (var i=0; i<6; i++) {
if (slotarray[i] == '') {
slotarray[i] = shortsrting;
slotid = 'slot' + i;
document.getElementById(slotid).value = longstring;
break;
}
}
}
With clearing at the moment of creating: ( Array('','','','','','') ), and textbox .value=''; its working as it should.
But then i figured out that i need function to clear textbox and bound array field. Not all but one specific for one clic. So instead of 6 functions i start to wrote
clear this field
for each of textbox, with different numbers and ids ofcourse, and clearing function:
function clear(arrayid, slotid) {
slotarray[arrayid] = '';
document.getElementById(slotid).value = '';
}
But this function do not clearing textbox neither array. I see that textbox has text, and i know that array isn't cleared because first function works finding first empty object...
What am i doing wrong here? its definition of "empty"/"cleared" filed/textbox? maybe i need to use more complex conditions? maybe it is something else.
Maybe i don't need array (i can manage to get rid of short-codes) and just make functions work only on textboxes?
Ok - i prepared jsfiddle demo with this, but even populating don't work..

You can't use the keyword clear because refers to the (deprecated) function document.clear; so try to change the name of your "clear" function.
Ok, whatever you have written is fine. Just change to way you call your javascript.
Here is jsfiddle: http://jsfiddle.net/BYt49/20/
I need to pass a variable to a javascript function which will then perform calculations and return the answer to another edit box on a form. I need to pass as I have 10 lines of edit boxes and dont want to have 10 seperate javascript functions.
function calc_totalcost(line)
{
$line_qty=line+"_qty";
$line_totcost=line+"_totcost";
$line_unitcost=line+"_unitcost";
$totcost=$line_qty.value*$line_unitcost.value;
document.getElementById('$line_totcost').value = $totcost;
}
on the html:
onchange="calc_totalcost('L1')"
So, on editbox 1 for L1_edit1 I need to send L1 to the function, which will then convert to 'L1_qty' which is an editbox (input) name where it will perform calculations using its contents. Hope that makes sense?
Thanks
You have a few issues, including the last line in the function which does not need the document.getElementById whereas all the others do need it.
function calc_totalcost(line) {
var $line_qty = document.getElementById(line+"_qty");
var $line_totcost = document.getElementById(line+"_totcost");
var $line_unitcost= document.getElementById(line+"_unitcost");
var $totcost=$line_qty.value*$line_unitcost.value;
$line_totcost.value = $totcost;
}
