JavaScript - Dom Range

Hi all,
can someone help me what is the right syntax to use for field that carry hidden value same as autoincrement value in db. The form was able to add n delete this value from db make it the hidden value keep changing. it is possible to check range validation for the value?

in this case the hidden value is sid.

How to correct the line below?
--> var chkVal = theForm.("score1"&&sid).value

the full script as below.

<script>
function Form1_Validator(theForm)
{
// require that the To Field be greater than or equal to the From Field
var chkVal = theForm.("score1"&&sid).value
var chkVal2 = theForm.("score2"&&sid).value
if (chkVal != "" && !(chkVal >= chkVal2)){
alert("The \"Score Range 2\" value must be greater than the \"Score Range 1\" value.");
theForm.("score2"&&sid).focus();
return (false);

}

}
</script>

Hi,
i have a problem to validate time range in javascript. i've search in the website and found some example.
below is the my coding

Code:

function timeCheck(){
	branchCode = <%=sessionUser.getBranchCode()%>;
	var d = new Date();	
	var curr_hour = d.getHours();
	var curr_min = d.getMinutes();
	if (curr_min < 10){
	curr_min = "0" + curr_min
	}
	var currtime = curr_hour + ":" + curr_min;

   	if(branchCode >= 1 && branchCode <= 5){
    	st = "7:30"; et = "9:00"; 
   	} else if(branchCode >= 6 && branchCode <= 10){ 
    	st = "9:01"; et = "10:30";
   	} else if(branchCode >= 11 && branchCode <= 15){ 
    	st = "10:31"; et = "12:00";
   	} else if(branchCode >= 16 && branchCode <= 20){ 
    	st = "12:01"; et = "13:30";
   	} else if(branchCode >= 21 && branchCode <= 26){ 
    	st = "13:31"; et = "15:00";
   	} else if(branchCode >= 27 && branchCode <= 31){ 
    	st = "15:01"; et = "16:30";

   	} 

	if(validate_time(currtime,st,et)){
		alert("Cannot access this page");
		location.href='<%=request.getContextPath()%>/security/welcome.do';
	} 
}

function validate_time(currtime,st,et ){    
   	currtime = currtime.split(/:/);        
   	st = st.split(/:/);        
   	et = et.split(/:/);
   	        
   	return (
   		currtime[0] < st[0]         
   		|| currtime[0] > et[0]              
   		|| (currtime[0] == st[0] && currtime[1] < st[1])             
   		|| (currtime[0] == et[0] && currtime[1] > et[1])
   	);  
   	//return TRUE if time not in range    
}

i want to control user's access to the page. they can only access within the range given.
example:
current time = 10:14
st = 9:01
et = 10:30
When I test, the currtime[0] < st[0] return true.
I don't understand why the statement return true. can someone help me?
Thanks in advance.

Thank You for your time

I want to validate two a date range using javascript, so that my program would check startdate less than end date.

The below function only check the year, and it works.





Code:

function validate()
{

var start=document.entry.datum1.value;
year = start.substr(0, 4);
month = start.substr(5, 2);
dayval = start.substr(8, 2);

var end=document.entry.datum2.value;
year1 = end.substr(0, 4);
month1 = end.substr(5, 2);
dayval1 = end.substr(8, 2);


var myDate=new Date();
myDate.setFullYear(year,month,dayval);
var today = new Date();
today.setFullYear(year1,month1,dayval1);

if (myDate> today)
  {
  alert("The start date must come before the end date");
  return false
  }

return true;
}

But I have write a function for checking the whole date value and it didnt work.
My date is in format-
2008-10-23(yyyy-mm-dd)

Code:

function validate()
{
var start=entry.datum1.value;
year = start.substr(0, 4);
month = start.substr(5, 2);
dayval = start.substr(8, 2);

intyear = parseInt(year, 10);
intmonth = parseInt(month, 10);
intdayval = parseInt(dayval, 10);

var end=entry.datum2.value;
year1 = end.substr(0, 4);
month1 = end.substr(5, 2);
dayval1 = end.substr(8, 2);

intyear1 = parseInt(year1, 10);
intmonth1 = parseInt(month1, 10);
intdayval1 = parseInt(dayval1, 10);

var startDate = Date.parse(intyear,intdayval,intmonth);
   var endDate = Date.parse(intyear1,intdayval1,intmonth1);

if (startDate > endDate)
  {
  alert("The start date must come before the end date");
  return false;
  }
return true;

}

Please help

Hi,

I am trying to link the <input type="range" min="450" max="800" value="500" /> to a CSS style for an AP box so when you move the slider
it then changes the Css style (top:--px). allowing the Ap box to move with the slider.

(important to work in Chrome)

Here is the code:
[CODE]
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<title>Untitled Document</title>
<style type="text/css">
<!--
#apDiv1 {

top:34px;
width:141px;

}
-->
</style>
</head>

<body>

<div id="apDiv1"><p>have an image in here. Need to make this box move up and down with the slider.</p></div>

I have tried a number of way but can't get it, I am sure it is simple.

Hi all,

I am trying to wrap a text selection with BBCode. I have it working, but there is one final part I need help with.

First, here's the code I'm using:
Code:

    var range = ed.selection.getRng(true);
    var s = ed.dom.create('span', {}, '');
    range.surroundContents(s);
    s.innerHTML = open + s.innerHTML + close;
    ed.selection.select(s);

This is an explanation of each line:
get the user's selection as a W3C compatible range create an empty <span> element surround the selection range with the span convert the selection from "selection" to "[bbcode]selection[/bbcode]" by using innerHTML select the new <span> element
Of course, selecting the span ALSO selects the BBCode open and close tag... like in this pictu



So, the last thing I need to do (the whole point of this post)... how do I MOVE the range start and end points so that only the selection is selected and NOT the whole thing?

I will greatly appreciate if someone can tell me how to move those selection start and end points...

Thanks!

So I've got my code ready to generate a random number between a certain range and printing it out in text. What I'm trying to accomplish with this code is to print the actual image as well as the text.

I'm aware that there is an error in my document.write line, and that it's not the best solution. I was hoping for some suggestions to change/improve this last bit. Thanks in advance!

Code:

<html>
<title>RANDOM IMAGE TO NUMBER RANGE</title>
<body>
<center>
<script language="javascript" type="text/javascript">
var ranges = [
    { from: 11, image: "image4.jpg" },
    { from: 1, image: "image3.jpg" },
    { from: -9, image: "image2.jpg" },
    { from: -20, image: "image1.jpg" }      
];

var random_num = (Math.round((Math.random()*41)+-20));
var image = "default";

for(var i = 0; i < ranges.length; ++i) {
    if(random_num >= ranges[i].from) {
        image = ranges[i].image;
        break;
    }
}
{
document.write("Text: " + random_num + " Text, " + " Image: = " + image);
{
document.write('<img src="images/' + ranges[i].image);
}
}
</script>
<br></br>
<div>
CLICK <a href="javascript:history.go(0);">REFRESH or F5</a> FOR A RANDOM IMAGE on NUMBER-RANGE.
</div>
</center>
</body>
</html>

Hello,
First I would like to say I am not a coder.
I would like to have a specific date range in years entered into a text box and if anything else is entered a pop up alert would appear. The date range would be from 1912 to 2002. Any help with this would be greatly appreciated.

I am using Joomla 2.5 and a form constructor called RS Form Pro That allows JS to be used.

This is the Javascript I am trying to use:

Code:

<script type="text/javascript">
function checkDate(theForm) 
year=document.getElementById('YearBorn').value;
if(year<1912 || year>2002)
{
  alert("registration is restricted to those born between 1912 to 2002");
  return false;
  else {
  return true;
}
}
</script>

This is how I am trying to call it

Code:

onblur="return checkDate(this);"

I am not sure if I am calling it correctly or if the JS code is even correct. When the user enters the date and it is not within the date range I need the alert to pop up.

Thank you for any help you can provide

Hi, I am using jQuery datepicker's date range, I have a dynamic form where date range fields are added dynamically, for this reason I have set the two selectors for jQuery date range to classes.

Below is my code:

Code:

$( ".datepicker_start_date, .datepicker_end_date" ).livequery(function() {
		var dates = $( ".datepicker_start_date, .datepicker_end_date" ).datepicker({
		  defaultDate: "+1w",
		  changeMonth: false,
		  dateFormat: 'dd-mm-yy',
		  numberOfMonths: 1,
		  onSelect: function( selectedDate ) {
			  var getclass = $(this).attr("class");
			  var option = getclass.indexOf("datepicker_start_date") != -1 ? "minDate" : "maxDate",
				  instance = $(this ).data( "datepicker" ),
				  date = $.datepicker.parseDate(
					  instance.settings.dateFormat ||
					  $.datepicker._defaults.dateFormat,
					  selectedDate, instance.settings );
			  dates.not( this ).datepicker( "option", option, date );
		  }
		});
	});

The above works perfect if I have just two field to range the date such as fields with class .datepicker_start_date and .datepicker_end_date. But if I have multiple fields like have 3-4 more date range fields, it will just mess the dates and add dates of field1 to field 3 and vice versa.

I would appreciate if someone could help.

Many Thanks

I'm wanting to put a piece of code on my website that will display when our next meeting will be. We have 2 meetings per month. I'm thinking what I need to do is create a code that gets the current month, day of month, and year then combines it together somehow, and if that combination is in a certain range a particular statement, "Next meeting is MM, DD YY." or "Next meeting is today." is displayed.

If date is equal to or between 01012012 and 01112012, "Next meeting is January, 12 2012" is displayed.
If date is equal to 01122012, "Next meeting is today" is displayed.
If date is equal to or between 01132012 and 01252012, "Next meeting is January, 26 2012" is displayed.
If date is equal to 01262012, "Next meeting is today" is displayed.
...that kind of thing.

How would I combine the month, day of month, and year?
Would 48 if statements be what I need to do?

Sorry, I'm pretty new to javascript. If there's a better way to do this, please let me know.

Thanks,

CJ

I'm working with datepickers to select a date range for my travel site (so they are a departure date and a return date). There are two datepickers and I can't get the min date on the first calendar set to today, and I also can't figure out how to get the date fields to clear if the user clicks the browsers refresh button - please help!

Here's the javascript code I'm currently trying to run:
$(function() {
var dates = $("#datepicker1, #datepicker2").datepicker({
defaultDate: '',
minDate: '+0m +0w +0d', // this isn't working to set the earliest selectable date to today
maxDate: '+0m +0w +365d', // but oddly enough this one works to make sure users can't select a date farther than a year out
numberOfMonths: 2,
beforeShow: function() {
var other = this.id == "from" ? "#datepicker2" : "#datepicker1";
var option = this.id == "from" ? "maxDate" : "minDate";
var selectedDate = $(other).datepicker('getDate');

$(this).datepicker("option", option, selectedDate);
}
}).change(function(){
var other = this.id == "from" ? "#datepicker2" : "#datepicker1";
if($('#datepicker1').datepicker('getDate') > $('#datepicker2').datepicker('getDate'))
$(other).datepicker('setDate', $(this).datepicker('getDate'));
});
});

// this is the function I wrote to try to clear the fields when browser refresh is clicked but it doesn't do anything
function clearInp() {
document.getElementById('datepicker1').value = "";
document.getElementById('datepicker2').value = "";
}


Here's the corresponding HTML code:
<form method="POST" name="myForm2" class="calendars">
<input id="datepicker1" type="text" name="departure_date" class="dates" size="15" maxlength="25" />
to
<input id="datepicker2" type="text" name="return_date" class="dates" size="15" maxlength="25" />
</form>

Thanks in advance!
