我可以在表单初始化期间生成数据表。（JSF）。然后我想编写 javascript 来从 rich:dataTable 值读取数据

<f:view>
  <html>
    <head>
      <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />

      <script type="text/javascript">
            function getTableValue()
            {
                //Here i want to write code for get one by one value  
                //from rich:datatable content
            }
      </script>

    </head>
    <body>
      <h:form id="tableForm" binding="#{DataTable.initForm}">

        <rich:dataTable id="salesTable" value="#{DataTable.saleList}" var="data">
          <f:facet name="header">
            <rich:columnGroup>
              <rich:column>
                <h:outputText value="Sales" />
              </rich:column>
            </rich:columnGroup>
          </f:facet>
          <rich:column>
            <h:outputText value="#{data.salesPercentage}" />
          </rich:column>
        </rich:dataTable>

        <input id="tableButton" type="button" value="getDataTableValue" onclick="getTableValue()" />

      </h:form>
    </body>
  </html>
</f:view>

首先从文档中获取表格（右键单击页面，执行查看源代码以查看自己生成的id）。

var table = document.getElementById('tableForm:salesTable');

然后从表体中获取行作为数组。

var rows = table.getElementsByTagName("tbody")[0].getElementsByTagName("tr");

然后循环行并从行中获取单元格作为数组。

for (var i = 0; i < rows.length; i++) {
    var cells = rows[i].getElementsByTagName("td");
}

然后循环单元格并获取内容。

for (var j = 0; j < cells.length; j++) {
    var cell = .cells[j];
    alert(cell.innerHTML);
}

另请参阅：

First get the table from the document (rightclick page, do View Source to see generated id yourself).

var table = document.getElementById('tableForm:salesTable');

Then get the rows as array from the table body.

var rows = table.getElementsByTagName("tbody")[0].getElementsByTagName("tr");

Then loop over rows and get the cells as array from the row.

for (var i = 0; i < rows.length; i++) {
    var cells = rows[i].getElementsByTagName("td");
}

Then loop over the cells and get the content.

for (var j = 0; j < cells.length; j++) {
    var cell = .cells[j];
    alert(cell.innerHTML);
}

function processDelete()
{
   var table = document.getElementById('AluminumPricingTab:forecastYearList');     var rows = table.getElementsByTagName("tbody")[0].getElementsByTagName("tr"); var yearAdd = "";
    for (var i = 0; i < rows.length; i++) {
        //alert("rows:" + i);       var cells = rows[i].getElementsByTagName("td");     var checked = document.getElementById("AluminumPricingTab:forecastYearList:"+i+":deleteSelectedRowCHK").checked;
        //alert("checked:" +checked); 
        if (checked)
        {
