How to highlight rows of extended datatable when mouse is over in jsf?

问题

I am trying to do highlight the rows of the extended datatable when mouse is over. Here is my datatable:

<rich:extendedDataTable onrowmouseover ="this.style.backgroundColor='#B5F3FB'" onrowmouseout="this.style.backgroundColor='white'" value="#{moneyTransferManager.allAccounts}" var="accounts"
                                        selection="#{extTableSelectionBean.selection}" id="table" frozenColumns="2"
                                        style="height:170px; width:484px;">
                    <a4j:ajax execute="@form" event="selectionchange" listener="#{extTableSelectionBean.selectionListener}"
                              render=":res"/>
                    <f:facet name="header">
                        <h:outputText value="Hesaplarım"/>
                    </f:facet>
                    <rich:column width="120px;">
                        <f:facet name="header">
                            <h:outputText value="Hesap Numarası"/>
                        </f:facet>
                        <h:outputText value="#{accounts.accountNumber}"/>
                    </rich:column>
                    <rich:column width="120px;">
                        <f:facet name="header">
                            <h:outputText value="Para Birimi"/>
                        </f:facet>
                        <h:outputText value="#{accounts.accountCurrency}"/>
                    </rich:column>                        
                </rich:extendedDataTable>

This one highlights only if row is clicked. Then i tried the following javascript code:

<script type="text/javascript">

$("tr").not(':first').hover(
  function () {
    $(this).css("background","yellow");
  }, 
  function () {
     $(this).css("background","");
  }
);

</script>

But this time when mouse is over, all of the rows are highlighted. Can anyone help me with this?

Thanks

Edit: This time i tried that javascript code:

<script type="text/javascript">
    $(function() {
        $("tr").not(':first').hover(
                function() {
                    $(this).css("background", "yellow");
                },
                function() {
                    $(this).css("background", "");
                }
        );
    })
</script>

But still, when the mouse is on one row, every rows are highlighted. What am i doing wrong here?

Edit 2: I also tried this:

<rich:extendedDataTable onrowmouseover ="this.style.backgroundColor='#B5F3FB'" onrowmouseout="this.style.backgroundColor='white'"

this time it works, but when mouse is on 1st or 2nd column, first 2 are highlighted and when mouse is on 3rd or 4th colum, the 3th and 4th rows are highlighted together, i mean 1-2 are highlighted together and 3-4 are together

回答1:

Using onrowmouseover and onrowmouseout worked fine on my end. Try using rowClass attribute of <rich:extendedDataTable> and define a rule in your stylesheet like so.

.test:hover {
    background-color: yellow; 
}

And do

<rich:extendedDataTable  rowClass="test">

Remember to set your <h:outputStylesheet> in <h:head>
