Limit size of textarea
Does anyone know of a way to limit the number of characters in a text area?
I have a form in a php page. The page writes the information of the form into a file. IF too much text gets entered, my display page gets messes up. I want to be able to limit the text entered in the textarea. Is this even possible? |

RE: Limit size of textarea
here is some code that will prevent a user from entering more than the specified number of characters in a textarea.
<script language="javascript"> var text1; function checklength(i) { var txt; txt=document.form.textarea1.value; n=txt.length; if (n>i) //i is the maxlength of textarea which we have set to 50 { alert('Text overflow'); document.form.textarea1.value=text1; return; } text1=document.form.textarea1.value; } </script> <body> <form name="form"> <textarea name="textarea1" onkeydown="checklength(50)"></textarea> </form> </body> by changing the number in the checklength() function call, you can specify any length you like |
