}
function checkStatus(notify) {
var employee = "John Peter";
var ss = SpreadsheetApp.getActiveSpreadsheet();
var mainSheet = ss.getSheetByName("MAIN");
var data = mainSheet.getDataRange().getValues();
for (var j = 0; j < data.length; j++){
var row = data[j];
var mainSheet2 = row[4];
var mainSheet3 = row[0];
var status = (mainSheet2 =="IN" && mainSheet3 == employee) ;
if (status == true){
var notify = employee +" You Are In"
return notify;
}
else{
var status = (mainSheet2 =="OUT" && mainSheet3 == employee) ;
if (status == true){
var notify2 = employee +" You Are Out"

Index.html
<body>
<div>
<button onclick="onStatus()">Check Status</button>
<font color='Green' id="status" onbeforeprint="onStatus" ></font>
</div>
<script>
function onStatus() {
google.script.run.withSuccessHandler(updateStatus) // Send the backend result to updateStatus()
.checkStatus(); // Call the backend function
}
function updateStatus(notify) {
document.getElementById('status').innerHTML= notify;
}
</script>
</body>
推荐答案
您可以在页面加载时调用此函数，如下所示.在您的body标签结束之前，在结尾处添加此脚本.
You can invoke this function at page load like below. Add this script at then end, just before your body tag ends.
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js">
</script>
<script>
// The code in this function runs when the page is loaded.
$(function() {
google.script.run.withSuccessHandler(updateStatus)
.checkStatus();
});
</script>
