Hi,
There are these struts tags in my jsp. I need to write a javascript function so
that when
a button addrow is clicked a new row withthese 2 dropdown lists(tables, columns)
is displayed. how to add a row with javascript function.
the second dropdown options depend on the table selected in the first dropdown.
how do I write a onchange function to get the columns of the table selected.
I have the javascript function to get tables and columns.
<nested:iterate id="conversion" name="updateForm" property="rowSet.rows"
type="com.net.menuentry">
<TR class=tblcellwhite>
<TD height=21>
<nested:select name="rows" property="repColumn.repTable.repTableId">
<logic:iterate id="repTable" name="updateForm" property="tableList"
type="com.net.RepTable">
<html:option
value="<%=repTable.getRepTableId().toString()%>"><%=repTable.getDisplayName()%></html:option>
</logic:iterate>
</nested:select>
</TD>
<TD>
<nested:select name="rows" property="repColumn.repColumnId">
<logic:iterate id="repTable" name="updateForm" property="tableList"
type="com.cnet.RepTable">
<nested:equal name="conversion"
property="repositoryColumn.repositoryTable.repTableId"
value="<%=repTable.getRepTableId().toString()%>">
<nested:iterate id="repColumn" name="repTable" property="repColumns"
type="com.cnet.RepColumn">
<html:option
value="<%=repColumn.getRepColumnId().toString()%>"><%=repColumn.getDisplayName()%></html:option>
</nested:iterate>
</nested:equal>
</logic:iterate>
</nested:select>
</TD>
function getTables() {
var tables = [
<%
List list = updateForm.getTableList();
if (list != null) {
int tableCount = list.size();
for(int i=0; i<tableCount; i++) {
RepTable table = (RepTable) list.get(i);
out.write("\"" + table.getDisplayName() + "\"");
if (i<tableCount-1) {
out.write(" ,");
}
}
}
%>
];
return tables;
}
function getColumnList(tableIndex) {
var columnList = [
<%
if (list != null) {
int tableCount = list.size();
for(int i=0; i<tableCount; i++) {
RepTable table = (RepTable) list.get(i);
Set columns = table.getRepColumns();
if (columns != null) {
out.write("[ ");
int columnCount = columns.size();
int col = 0;
for (Iterator iter=columns.iterator(); iter.hasNext();) {
RepColumn column = (RepColumn) iter.next();
out.write("\"" + column.getDisplayName() + "\"");
if (col<columnCount-1) {
out.write(" ,");
}
col++;
}
out.write(" ]");
if (i<tableCount-1) {
out.write(",\r\n");
}
}
}
}
%>
];
return columnList[tableIndex];
}
