我试图了解如何将服务器端分页用于动态数据(我看到示例:http: //developer.yahoo.com/yui/examples/datatable/dt_dynamicdata.html)。
我的问题是我无法自定义我的请求,当我尝试分页时,我的请求是:qct-list.htmlsort=geneid&dir=asc&startIndex=50&result=25
请求应采用以下形式:qct-list.html?name=cd4&symbol=cd4&start=0&limit=25 或 qct-list.html?name=cd4&symbol=cd4&start=25&limit=50 ...
这是我的代码的副本(部分):
var myColumnDefs = [
{key:"geneid", label:"Gene", sortable:true},
{key:"name", label:"Name", sortable:true},
{key:"symbol", label:"Symbol", sortable:true},
{key:"lastupdated", label:"Last Updated", formatter:"date", sortable:true},
{key:"lastmodified", label:"Last Modified", formatter:"date", sortable:true}
];
var myDataSource = new YAHOO.util.DataSource("qct-list.html");
myDataSource.responseType = YAHOO.util.DataSource.TYPE_JSON;
myDataSource.connXhrMode = "queueRequests";
myDataSource.responseSchema = {
resultsList: "geneItemList",
fields: ["col","qv","limit","start","geneid","name","symbol","lastupdated","lastmodified"],
metaFields: {
totalRecords: "totalRecords" // Access to value in the server response
}
};
var qctPaginator = new YAHOO.widget.Paginator({
rowsPerPage: 25,
totalRecords : YAHOO.widget.Paginator.VALUE_UNLIMITED,
template: YAHOO.widget.Paginator.TEMPLATE_ROWS_PER_PAGE,
rowsPerPageOptions: [25,50,75,100]
});
var myRequestBuilder = function(ostate, oSelf) {
oState = oState || {pagination:null};
var name = Dom.get('dt_input_name').value;
var symbol = Dom.get('dt_input_symbol').value;
var start = (oState.pagination) ? oState.pagination.recordOffset : 0;
var limit = (oState.pagination) ? oState.pagination.rowsPerPage : 25;
return "?name=" + name + "&symbol"+ symbol + "&start=" + start + "&limit=" + limit;
}
var oConfigs = {
dynamicData: true, // Enables dynamic server-driven data
selectionMode: "single",
paginator: qctPaginator ,
generateRequest : myRequestBuilder,
paginationEventHandler : YAHOO.widget.DataTable.handleDataSourcePagination,
initialRequest: "?name=&symbol=&start=0&limit="
};
var myGeneListTable = new YAHOO.widget.DataTable("geneListTable", myColumnDefs, myDataSource, oConfigs);
myGeneListTable.handleDataReturnPayload = function(oRequest, oResponse, oPayload) {
oPayload.totalRecords = oResponse.meta.totalRecords;
return oPayload;
}
有人可以解释如何使用 DataTable 的分页以及如何个性化请求吗?
