The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

formatting a textbox with a specific format

Zone: Miscellaneous Web Development

Tags: format, textbox, text, box

hello,

i have a sort of validation that i need to implement in my form.

there are textboxes that should accept only numbers. as the user types the appropriate commas should appear accordingly.

example: the user types 25000 but in the text box it appears as 25,000 automatically.

i dont want the user to input points as there wont be any decimals in the values. he/she should only input the number.

could i get some help on it with javascript?

peace,

rdmjrb:

Basically you would have a function that gets fired onKeyPress that firstly checks the user only types numbers and second checks the length and if the length is 3/6/9, etc then it sticks a ',' in the string.

This is a pretty complicated piece of javascript for only 30 points, however this is one of the best javascript sites I have come across: http://www.dynamicdrive.com that may help your cause.

oooppppssss

<input type="text" name="numField" onKeyPress="formatField(this)" maxlength="6">

06.23.2003 at 11:35PM PDT, ID: 8787255

fmh002:

thnx for the link rdmjrb, i would have given it 60 points but im out of points right now.

jaysolomon!!! sup? i see you got what i wanted. your script works fine with maxlength=6. in my environment it is a bit difficukt coz the digits always exceed the max length=6. i live in a country where a dollar costs a 1000 shillings.

i would like to go to a maximum of 9. could you help me with the commas? it's working fine right now coz in my question i gave a 6 digit example. i see my mistake.

thnx once again jaysolomon

06.23.2003 at 11:42PM PDT, ID: 8787274

fmh002:

i've also noticed that if i type in 2500 it gives it a comma as well -> 25,00... ooops.

06.24.2003 at 03:53AM PDT, ID: 8788416

fmh002:

i'd also like have only numbers entered. at the moment there is no restriction on the input in your script.

peace,

jaysolomon:

here is a link that may be very helpful.

Try it out and if you still need help just let me know. I will continue to write a shorter script.

sh!t i forgot the link brb....

jaysolomon:

http://www.mredkj.com/javascript/numberFormat.html#tryit

there is the link

after you look at that and if you decide to go that route, we can then see your form and create the Number Only function

06.24.2003 at 09:03AM PDT, ID: 8790425

fmh002:

sup jaysolomon

wow that script on that page is quite complex and trying to customize it for my form is way beyond my capabilities. but there's a setback, that try it button does the formatting. i am sure there must be a way to make that function trigger onkeypress or something? dont you think so? well, i have decided to go that route but that button shouldn't do the function, it should be done on the textbox itself.

peace

06.24.2003 at 09:05AM PDT, ID: 8790442

fmh002:

that script has many functions, could you make it shorter? do only the comma placements

06.25.2003 at 08:54AM PDT, ID: 8798621

fmh002:

people i need help, i've increased points for that matter...

jaysolomon:

is this going to be a currency format, or do you just want a comma

also is it always 5 numbers or what is the max amount of numbers

06.25.2003 at 09:12AM PDT, ID: 8798777

fmh002:

i just want a comm and my max amount of numbers could be 9,999,999

06.25.2003 at 01:01PM PDT, ID: 8800470

jaysolomon:

try this

<html>
<head>
<title></title>
<script type="text/javascript">

</script>
</head>

<body>
<form name="form1" method="post" action="">
<input type="text" name="fieldName" onChange="return addCommas();">
<input type="text" name="textfield">
</form>
</body>
</html>

fmh002:

jaysolomon:

Uh why the grade of a "C"?

You asked for commas, thats what you got

06.26.2003 at 08:45AM PDT, ID: 8806248

fmh002:

hey man im sorry for grading a C on that. i'd make it up to you if you could help me with some other problem i got.

06.26.2003 at 08:49AM PDT, ID: 8806286

jaysolomon:

you can post a Question in Community Support asking them to change this grade.

Now whats the Problem?

06.26.2003 at 08:54AM PDT, ID: 8806327

fmh002:

Response.Write "<SELECT name=studentid onchange=""studentname.value = this.value;"">"

I think it should be like so

Response.Write "<SELECT name=studentid onchange='this.form.studentname.value = this.value;'>"

and

Response.Write "<SELECT name=studentname onchange='this.form.studentid.value = this.value;'>"

This is contredicting itself to me

and this is why you are getting the same results in the 2 DB fields

i have already posted on the community support, jay am i ok with u now?
