And also want to display in textfield is 1234567890.Please share me some ideas and links

Answer 1

You can create your struts 2 text field which will accept max 20 character like below.

Code:

var value = "12345678912345678912";
$('#my').val(value.substr(0,10));

for dispaly only 10 digit you need to use javascript or jquery like below code.

Jquery Code:

 var value = "12345678912345678912"; $('#my').val(value.substr(0,10)); 

if value is not an String then you can use.

 var value = 12345678912345678912; $('#my').val(value.toString().substr(0,10)); 

Answer 2

Using this code you can achieve it

<s:textfield name="fieldname" value="12345678901234567890" size="10"/>

the display area of the field not exceed a 10 characters. However, the filed can contain more than 10 characters.

Answer 3

使用固定大小，例如：

<input type="text" value="12345678901234567890" style="width:50px" />

Answer 4

例如：输入类型=“文本”值=“12345678901234567890”style =“width：50px”maxlength =“20”
