Textual Data Over XHR
This example demonstrates how to populate a DataTable with delimited text data over XHR. In the second instance, the data includes header data as the first row, which is parsed out with a custom implementation of the DataSource method doBeforeCallback().
<script type="text/javascript"> YAHOO.util.Event.addListener(window, "load", function() {
YAHOO.example.XHR_Text = function() {
var formatUrl = function(elCell, oRecord, oColumn, sData) {
elCell.innerHTML = "<a href="" + oRecord.getData("Url") + "" target="_blank">" + sData + "</a>";
};
var myColumnDefs = [
{key:"Name", sortable:true, formatter:formatUrl},
{key:"Phone"},
{key:"City"},
{key:"Rating", formatter:YAHOO.widget.DataTable.formatNumber, sortable:true}
];
var myDataSource = new YAHOO.util.DataSource("yui_2.7.0b-assets/datatable-assets/php/text_proxy.txt");
//myDataSource.responseType = YAHOO.util.DataSource.TYPE_TEXT;
myDataSource.responseSchema = {
recordDelim: "\n",
fieldDelim: "|",
fields: ["Name","Address","City","Phone",{key:"Rating",parser:"number"},"Url"]
};
var myDataTable = new YAHOO.widget.DataTable("text", myColumnDefs,
myDataSource, {caption:"Example: Textual Data Over XHR"});
var moreColumnDefs = [
{key:"Restaurant", sortable:true, formatter:formatUrl},
{key:"Location"},
{key:"Town"},
{key:"Stars", formatter:YAHOO.widget.DataTable.formatNumber, sortable:true}
];
var anotherDataSource = new YAHOO.util.DataSource("yui_2.7.0b-assets/datatable-assets/php/text_with_headers_proxy.txt");
anotherDataSource.responseType = YAHOO.util.DataSource.TYPE_TEXT;
anotherDataSource.responseSchema = {
recordDelim: "\n",
fieldDelim: "|",
fields: ["Restaurant","Location","Town","Telephone",{key:"Stars",parser:"number"},"Url"]
};
// Upgrade note: As of 2.5.0, the second argument is the full type-converted
// response from the live data, and not the unconverted raw response
anotherDataSource.doBeforeCallback = function(oRequest, oFullResponse, oParsedResponse) {
// Remove the first result (i.e., the headers);
oParsedResponse.results.shift();
return oParsedResponse;
};
anotherDataTable = new YAHOO.widget.DataTable("textWithHeaderData", moreColumnDefs,
anotherDataSource, {caption:"Example: First Record Holds Header Data"});
return {
oDS: myDataSource,
oDT: myDataTable,
oDS2: anotherDataSource,
oDT2: anotherDataTable
};
}();
}); </script>
