Later, wandering on the internet suddenly found a better text box word limit of the jquery plugin, simple and easy to use
The effect of the following figure
Copy Code code as follows:
<! DOCTYPE HTML PUBLIC "-//W3C//DTD XHTML 1.0 transitional//en" "Http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd ">
<title> about text box word limit function </tit le>
<script type= "Text/javascript" src= "jquery-1.2.6.min.js" ></script>
<script type= "text /javascript "src=" maxlength.js "></script>
<body>
<p>enter your Hobbie S (<50 characters) </p>
<textarea style= "width:300px" height:150px data-maxsize= "data-output=" Status1 "wrap=" virtual "></textarea><br/>
<div id=" Status1 "style=" Width:300px;font-weight: Bold;text-align:right "></div><br/>
<p>enter Your postal code (<6 characters) </p>
<input type= "text" name= "T1" size= "" data-maxsize= "6" >
</body>
Attribute Explanation:
Data-maxsize: The maximum number of words that the text field can accept. (important)
Data-output: If you want to animate the number of words in a text box in real time, this property sets the span or div ID that displays the word count. (The color of the words will change with the quantity)
If you do not modify its source file, add a JS reference, you only need to give your own text or textarea plus data-maxsize attributes on it.
About setting maximum values dynamically
Use the Setformfieldsize method:
Setformfieldsize ($field, maxsize, Outputfieldid)
Attribute Explanation:
$field: The jquery object of the Restricted text box (refer to the jquery document).
MaxSize: As with data-maxsize, the maximum number of words that the text field can accept.
Outputfieldid: The same as data-output.
Example:
Copy Code code as follows:
<script type= "Text/javascript" >
JQuery (document). Ready (function ($) {//fire on DOM ready
Setformfieldsize (JQuery (' #comment '), ' Charsremain ')
//});
</script>
Executed when the interface is loaded.
