问题描述
我在Google App脚本(表格)中有此HTML表单，该表单要求用户提供日期值，然后提交该值.HTML表单运行.唯一的问题是obj不记录.我不知道为什么会这样.
I have this HTML form in Google App Script(Sheets) that asks a user for a date value and then to submit the value. The HTML form runs. the only problem is the obj doesn't log. I can't figure out why this is.
HTML:
<!DOCTYPE html>
<html>
<head>
<base target="_top">
</head>
<body>
<form id="myForm">
<input type="date" name="startDate" value="" id="demo" >
<input type="button" style="font-family: verdana;" value="Submit" onclick="getStartDate()">
</form>
<script>
function success(msg) {
alert(msg);
}
function getStartDate(){
var form = document.getElementById("myForm").elements;
var obj ={};
for(var i = 0 ; i < form.length ; i++){
var item = form.item(i);
obj[item.name] = item.value;
}
google.script.run
.withSuccessHandler(success)
.getStartDate(obj);
google.script.host.close();
};
</script>
</body>
</html>
JavaScript:
The Javascript:
function getStartDate(obj){
Logger.log(obj)
}
这应该输出对象，但不会输出.
This should output the object but it doesn't.
感谢您的帮助！
推荐答案
此修改如何?
-
google.script.run通过异步处理工作.因此，在您的脚本中，由于google.script.host.close()，getStartDate()和success()无法运行. GAS端的 -
getStartDate()不返回值.因此，alert(msg)显示为undefined.
google.script.runworks by the asynchronous processing. So in your script,getStartDate()andsuccess()are not run due togoogle.script.host.close().getStartDate()at GAS side doesn't return values. Soalert(msg)showsundefined.
当以上几点反映到您的脚本中时，它如下所示.
When above points are reflected to your script, it becomes as follows.
请按如下所示修改Javascript.
Please modify Javascript as follows.
function success(msg) {
alert(JSON.stringify(msg)); // Modified
}
function getStartDate(){
var form = document.getElementById("myForm").elements;
var obj ={};
for(var i = 0 ; i < form.length ; i++){
var item = form.item(i);
obj[item.name] = item.value;
}
google.script.run
.withSuccessHandler(function(e) { // Modified
success(e);
google.script.host.close();
})
.getStartDate(obj);
};
气体:
function getStartDate(obj){
Logger.log(obj)
return obj; // Modified
}
注意:
- 如果您想将密钥提供给
Submit，请将name添加到< input type ="button" style ="font-family:verdana;"value ="Submit" onclick ="getStartDate()">. - 当然，您也可以将
google.script.host.close()移至success(). - If you want to give the key to
Submit, please addnameto<input type="button" style="font-family: verdana;" value="Submit" onclick="getStartDate()">. - Of course, you can also move
google.script.host.close()tosuccess().
Note:
如果这不是您想要的，请告诉我.我想修改它.
If this was not what you want, please tell me. I would like to modify it.
