我有一个kendo数据源,它可以调用我的api,我只限制了10页。我的问题是寻呼机不会回到第一页。例如,当我打电话和我的api并收到50个结果时,我将有5页,每页10个项目。我选择转到第五页,然后我再拨打一个电话,只收到10个项目。然而,校准完成我仍然在第5页;它不会重置为第一页。
var dataSource = new kendo.data.DataSource({
page:1, << From what I read this is suppose to do the job
pageSize: 10,
transport: {
read: {
type: "POST",
url: location + "/api/ContentSearch/SearchRequest",
contentType: 'application/json',
beforeSend: function (req) {
req.setRequestHeader("Authorization", "Bearer " + token);
}
},
parameterMap: function (option, operation) {
return JSON.stringify(query);
}
},
change: function (e) {
var data = this.data();
$("#searchButton").prop("disabled", false);
$("#loadingGif").hide();
//kendoPager.page(1); << does not work
switch (data.length) {
case 0:
FeedBackMessage("No result found");
break;
case 500:
FeedBackMessage("Please check or refine the search");
break;
default:
$('#pager').show();
$('#descriptionColumn').show();
$("#listView").show();
$("#keyWordText").val("").data("kendoDropDownList").text("");
$("#searchText").val("");
}
return data;
},
error: function (e) {
$("#loadingGif").hide();
ErrorHandler(e.sender.transport.options.read.url, e.xhr.status, e.xhr.statusText, "Kendo datasource was not binded to the WebApi response", "", true);
}
});
function SubmitSearch(e) {
e.preventDefault();
query = {
SearchText: $("#searchText").val(),
KeywordText: generalContentKeywords.text(),
GlobalSearch: true
};
if (query.SearchText === "" && query.KeywordText === "Select Category") {
FeedBackMessage("Please enter a value");
}
else {
if (query.KeywordText === "Select Category") {
query.KeywordText = "";
}
$.when(TokenForWebApi()).then(function (adalToken) {
token = adalToken;
$('#pager').hide();
$('#descriptionColumn').hide();
$("#listView").hide();
$("#searchButton").prop("disabled", true);
$("#loadingGif").show();
dataSource.read();
});
}
};
var kendoPager = $("#pager").kendoPager({
dataSource: dataSource,
}).data("kendoPager");
答案 0 :(得分:0)
我解决了这个问题,通过更改我的提交函数来查看数据源是否有任何数据,如果它发现它重置,则重置将页面设置为1。我猜我以前的代码,我试图在数据源有任何页面值之前设置一个页面值。
function SubmitSearch(e) {
e.preventDefault();
query = {
SearchText: $("#searchText").val(),
KeywordText: generalContentKeywords.text(),
GlobalSearch: true
};
if (query.SearchText === "" && query.KeywordText === "Select Category") {
FeedBackMessage("Please enter a value");
}
else {
if (query.KeywordText === "Select Category") {
query.KeywordText = "";
}
$.when(TokenForWebApi()).then(function (adalToken) {
if (dataSource._pristineData.length) {
kendoPager.page(1);
}
token = adalToken;
$('#pager').hide();
$('#descriptionColumn').hide();
$("#listView").hide();
$("#searchButton").prop("disabled", true);
$("#loadingGif").show();
dataSource.read();
});
}
};
