Question

The following event is not getting invoked:

<script>
        $("#inputTxt").change(function() {
            alert("changed");
        }); 
 </script>

The code for inputTxt is as follows:

<p:inputText id ="inputTxt" name="inputTxt" value="#{article.description}"
                    style="border:none; box-shadow:none;"/>

The coloumn “articleDescription” is defined in a datatable named “articlesInformation” which is placed on a form “articleForm”.

On inspected the element, I found that the id of the inputText becomes – “articlesInformation:0:inputTxt”. Probably that is the issue.

Viewing page info says :

    <td role="gridcell">
       <div class="ui-dt-c">
        <input id="articlesInformation:0:inputTxt" name="articlesInformation:0:inputTxt"
         type="text" value="Description of Article 1"
         style="border:none; box-shadow:none;"
         class="ui-inputfield ui-inputtext ui-widget ui-state-default ui-corner-all" />
       <script id="articlesInformation:0:inputTxt_s"
  type="text/javascript">PrimeFaces.cw('InputText','widget_articlesInformation_0_inputTxt'
    {id:'articlesInformation:0:inputTxt'});
</script></div></td>

How should the jquery be defined for primefaces components?

Thanks,

Answer 1

When inputText is placed in datatable, primefaces gives it id = datatable_id:row_index:inputText_id. That is, the inputText in row 7 is given the id = datatable_id:7:inputText_id. Try the below …

<p:dataTable id="table_Details" var="dataItem" rowIndexVar="rowIndex">
     <p:column id="articleDescription" headerText="Article Description">
        <p:inputText id="inputTxt" name="inputTxt" value="#{article.description}" onchange="inputTextChanged(#{rowIndex})"/>
     </p:column>
</p:dataTable>

function inputTextChanged(rowIndex){
    var str = 'table_Details:' + rowIndex + ':inputTxt';
    var selected = $(document.getElementById(str));
    alert (selected.val());
}

Hope this helps
