Maxlength Issue - Javascript

2 New Member

Hi all,

I have a situation here. The below snippet is used to get a textarea, but I have not been able to figure out as to how I can limit the number of character the user enters.... (say limit to 20). I am looking for a maxlength type of function or something which would implement on same lines.

Expand|Select|Wrap|Line Numbers

 <OBJECT style="z-index:1;" classid="clsid:2D360201-FFF5-11d1-8D03-00A0C959BC0A" width="100%" height="100%" id="MSHTMLObject<%=editCounter%>" %>">

<PARAM NAME=ScrollbarAppearance VALUE=0>

</OBJECT>

Any suggestions would be most welcome.
Best regards,
Srinivasa

hi ...

you may use something like in the following example:

Expand|Select|Wrap|Line Numbers

 <html>

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

        function chk_txt(node, max_val) {

            var txt = node.value;

            var l   = txt.length;
 
            if (l > max_val) {

                node.value = txt.match(/.{20}/);

                l = node.value.length;

            }
 
            var no_dspl = document.getElementById('txt_length');

            no_dspl.innerHTML = l;

        }

    </script>
 
    </head>

    <body>

        <textarea id="my_txt" onkeyup="chk_txt(this, 20);" rows="5"></textarea>

        <br/>

        current no. of chars &nbsp;

        <span id="txt_length" style="color: red;">0</span>

    </body>

</html>

it uses a regular html-textarea instead of an embedded object ... why do you use that? may be the object itself has some properties you may use to limit the maxlength but in case you could use a normal html-textarea, you may use the sample above ...

kind regards

Hi Gits,

Your code looks good, however I would have to use the embedded object itself.
In this regard, could you provide me some solution or guide me to any write ups on the object so that I can check if there are any intrinsic properties i can make use of?

Best regards and thanks,
Srinivasa
