我是js的新手,我需要帮助在行之间使用html。
我有这个活动:
eventSource.addEventListener('Uptime', function(e) {
var parsedData = JSON.parse(e.data);
var tempSpan = document.getElementById("uptime");
var tsSpan = document.getElementById("tstamp");
tempSpan.innerHTML = parsedData.data;
tempSpan.style.fontSize = "28px";
tsSpan.innerHTML = "At timestamp " + parsedData.published_at;
tsSpan.style.fontSize = "9px";
}, false);
它会从我的Spark Core中侦听事件,并以状态更新我的网站。
我想要的是在我的div中显示的状态。
<div id="on"> </div>
这可能吗?

var deviceID = "";
var accessToken = "";
var eventSource = new EventSource("https://api.spark.io/v1/devices/" + deviceID + "/events/?access_token=" + accessToken);
eventSource.addEventListener('open', function(e) {
console.log("Opened!"); },false);
eventSource.addEventListener('error', function(e) {
console.log("Errored!"); },false);
<!--THIS IS THE METHOD I WANT INSIDE THE DIV-->
eventSource.addEventListener('Uptime', function(e) {
var parsedData = JSON.parse(e.data);
var tempSpan = document.getElementById("uptime");
var tsSpan = document.getElementById("tstamp");
tempSpan.innerHTML = parsedData.data;
tempSpan.style.fontSize = "28px";
tsSpan.innerHTML = "At timestamp " + parsedData.published_at;
tsSpan.style.fontSize = "9px";
var div = document.createElement("div")
div.innerHTML = parsedData.status;
document.body.appendChild(div);
document.getElementById("on").innerHTML = parsedData.status;
}, false);
}
</script>

为了更具特色,我试图在div中显示文字“Borte”
答案 0 :(得分:2)
在活动结束时,只需执行(假设status
是parsedData
内的值):
document.getElementById("on").innerHTML = parsedData.status;
假设你在页面上有div
,如果你没有,那么你必须先创建它:
var div = document.createElement("div")
div.innerHTML = parsedData.status;
document.body.appendChild(div);
