我有一个asp.net mvc视图,其中包含使用以下代码动态加载的一些部分:
$('#div1').load('controller1/action1', function() {
alert('Load was performed.');
});
$('#div2').load('controller1/action2', function() {
alert('Load was performed.');
});
加载的所有视图都将使用signalr连接。我无法多次启动连接,如下所示:
$.connection.hub.start().pipe(test).done(function () {
//....
});
我收到错误:
*SignalR: Connection has not been fully initialized. Use .start().done() or .start().fail() to run logic after the connection has started.*
因此我将start方法的返回值存储在全局变量中:
<script type="text/javascript">
window.connection = $.connection.hub.start();
</script>
我正在使用它如下:
$(document).ready(function () {
var initialMarketWatchData = null;
var marketWatchTicker = $.connection.marketWatch;
function initMarketWatch() {
return marketWatchTicker.server.getAllMarketWatchData().done(function (data) {
data.forEach(function (item) {
item.ask = item.ask.toFixed(5);
item.bid = item.bid.toFixed(5);
});
initialMarketWatchData = data;
$("#marketWatchGrid").data("kendoGrid").dataSource.data(data);
});
}
marketWatchTicker.client.updateMarketWatchData =
function (marketWatchData) {
try {
if (viewModelOrder.selectedInstrument == marketWatchData.symbol) {
viewModelOrder.updatePrice(marketWatchData.ask.toFixed(5), marketWatchData.bid.toFixed(5));
}
var tr = $("#marketWatchGrid").find("tr:contains('" + marketWatchData.symbol + "')");
var bg = '';
if (marketWatchData.direction == 1) {
bg = '154,240,117';
}
else {
bg = '255,148,148';
}
tr.find("td:nth-child(2)").html(marketWatchData.ask.toFixed(5));
tr.find("td:nth-child(3)").html(marketWatchData.bid.toFixed(5));
var current = tr.css('backgroundColor');
tr.animate({ backgroundColor: 'rgb(' + bg + ')' }, 150)
.animate({ backgroundColor: current }, 150)
} catch (e) {
console.log("exception: " + e.message);
}
}
window.connection.pipe(initMarketWatch).done(function () {
viewModelHomeIndex.setInstruments(initialMarketWatchData);
});
});
function selectSymbol(symbol) {
var tr = $("#marketWatchGrid").find("tr:contains('" + symbol + "')");
var ask = tr.find("td:nth-child(2)").html();
var bid = tr.find("td:nth-child(3)").html();
viewModelOrder.selectSymbol(symbol, ask, bid);
}
但在这种情况下,我的客户端函数在第一次加载视图时没有被调用。而且我没有收到任何错误。我点击F5后一切正常。
我该如何解决这个问题?
