jsf - Allow only digits to the filtered textbox (search filter) of dataTable in Primefaces -


is possible apply such validation filtered textbox provided datatable of primefaces customizing it.

the maximum number of characters textbox can hold can set using filtermaxlength="45" property of <p:column>. example.

<p:column headertext="headertext" sortby="#{obj.properyname}" filtermaxlength="45" filterby="#{obj.properyname}">     <h:outputtext value="#{obj.properyname}" /> </p:column>

i can't see such property perform other kind of validations such allowing specific characters, perhaps using regex.

anyway, need allow have digits, since there id column of type bigint (primary key, auto-increment) in mysql database mapped long datatype in entity classes.

is supported primefaces or there way customize it?

afaik primefaces doesn't has option. can use javascript solve that.

you have set id column want limit, input(use filter) have default id filter, process keydown event allow digits. example, create 1 form(id="form"), , nest 1 datatable(id="cars"),one column(id="cl2") , input's id filter, bind keydown event filter key user type:

<h:form id="form"> <script type="text/javascript">                 //<![cdata[                 $(document).ready(function() {                     $("#form\\:cars\\:cl2\\:filter").keydown(function(event) {                         // allow: backspace, delete, tab, escape, , enter                         if ( event.keycode == 46 || event.keycode == 8 || event.keycode == 9 || event.keycode == 27 || event.keycode == 13 ||                              // allow: ctrl+a                         (event.keycode == 65 && event.ctrlkey === true) ||                              // allow: home, end, left, right                         (event.keycode >= 35 && event.keycode <= 39)) {                             // let happen, don't                             return;                         }                         else {                             // ensure number , stop keypress                             if (event.shiftkey || (event.keycode < 48 || event.keycode > 57) && (event.keycode < 96 || event.keycode > 105 )) {                                 event.preventdefault();                              }                            }                     });                 });                 //]]>             </script> <p:datatable id="cars">       <p:column id="cl2" headertext="manufac" filtermatchmode="contains" filterby="#{carr.manufacturer}">   </p:datatable>
