我有一个情节,我正在创建一切工作正常,除了当我单击按钮时,它会为我的数据生成线条。如果我再次点击该按钮,它只会覆盖第一个 ajax 请求,而不是从头开始,这正是我想要的。请帮助这是我的ajax调用。
$('#process').click(function(e) {
var market = '&market=' + $('#market').val();
var productgroup = '&productgroup=' + $('#curve').val();
var from = '&from=' + $('#date_from').val();
var to = '&to=' + $('#date_to').val();
var lookback = '&lookback=' + $('.timeframe').attr('id');
var fullUrl = url + market + productgroup + from + to + lookback;
e.preventDefault();
$.ajax({
url: fullUrl,
type: "GET",
dataType: "json",
success: onDataReceived,
error: onError//,
// data: data
});
});
这是我的情节的选项
var options = {
series: {
lines: {
show: true,
lineWidth: .1
},
points: {
show: false
}
},
xaxis: {
mode: "time",
minTickSize: [1, "day"],
timeformat: "%m/%d/%Y",
panRange: timespan
},
yaxis: {
mode: "money",
tickDecimals: 2,
panRange: [0, 100],
tickFormatter: dollarFormatter
},
zoom: {
interactive: true
},
pan: {
interactive: true
}
};
这是创建情节的功能
var data = [];
$.plot("#placeholder", data, options);
这是我的 onDataReceived 函数
function onDataReceived(series) {
// Push the new data onto our existing data array
var count = 0;
for(var prop in series) {
if(series.hasOwnProperty(prop))
++count;
}
for(i=0;i<count;i++)
{
if (!alreadyFetched[series[i].label]) {
data.push(series[i]);
}
}
$.plot("#placeholder", data, options);
}
