问题1:此代码应该给予唯一的ID,以您的TextBox控件以及出ID号的任何间隙照顾。我通过使用函数getID来实现此目的,该函数跟踪数组中的可用id。每当我们删除一个元素,该索引的数组值就被设置为-1。我们使用indexOf搜索“-1”并跟踪未使用的ID。
var index = [];
// Array starts with 0 but the id start with 0 so push a dummy value
index.push(0);
// Push 1 at index 1 since one child element is already created
index.push(1)
function addkid() {
var div = document.createElement('div');
var id = getID();
// Set this attritube id so that we can access this element using Id
div.setAttribute("id","Div_"+id);
div.innerHTML = 'Child_' + id + ': <input type="text" name="child_' + id + '"/>' + ' <input type="button" id="add_kid()_' + id + '" onclick="addkid()" value="+" />' + ' <input type="button" id="rem_kid()_' + id + '" onclick="remkid('+id+')" value="-" />';
// inside of passing this parameter in remkid we pass id number
document.getElementById('kids').appendChild(div);
}
function remkid(id) {
// use the id arugment to get the div element using unique id set in addkid
try{
var element = document.getElementById("Div_"+id)
element.parentNode.removeChild(element);
index[id] = -1;
//id number is = index of the array so we set to -1 to indicate its empty
}
catch(err){
alert("id: Div_"+id)
alert(err)
}
}
function getID(){
var emptyIndex = index.indexOf(-1);
if (emptyIndex != -1){
index[emptyIndex] = emptyIndex
return emptyIndex
} else {
emptyIndex = index.length
index.push(emptyIndex)
return emptyIndex
}
}
<form action ="Your app script link here" method="post">
Name:
<input type="text" name="name">
<br/>
<div id="kids">
Child_1:
<input type="text" name="child_1">
<input type="button" id="add_kid()_1" onclick="addkid()" value="+" />
</div>
Phone:
<input type="text" name="phone">
<br/>
<input type="submit" name="submit" value="submit" />
</form>
问题2,3:可以将表单的值传递给使用表单标签的应用程序脚本:
<form action= "app script web app link" method ="post/get">
现在使用appscripts的数据访问,我们将不得不制作一个网络应用并获得一个链接。这将帮助你开始:https://developers.google.com/apps-script/guides/web
您将创建这样一个appscript:
function doPost(e) {
var ss = SpreadsheetApp.openById("Your Spd ID")
var sheet = ss.getSheetByName("Sheet1")
var response = []
response[0] = new Date()
response[1] = e.contentLength
response[2] = JSON.stringify(e.parameters)
sheet.appendRow(response)
return HtmlService.createHtmlOutput('<b>Hello, world!</b>');
}
而且你的工作表Sheet1将收到像这样的回应:
2/12/2017 14:17:37 47 {"parameter":{"submit":"submit","child_1":"asd","phone":"1234","name":"jagan"},"contextPath":"","contentLength":47,"queryString":null,"parameters":{"submit":["submit"],"child_1":["asd"],"phone":["1234"],"name":["jagan"]},"postData":{"type":"application/x-www-form-urlencoded","length":47,"contents":"name=jagan&child_1=asd&phone=1234&submit=submit","name":"postData"}}
This Works!谢谢@jagannathan alagurajan。一个问题:现在jsondata只包含动态文本框的值。是否也可以包含其他静态控件的值:例如“name”,“phone”或日期字段? – sifar786
我不确定我是否理解你的问题,只要他们在表单标记内,名称和电话值就会传递给应用脚本(
) –可以理解。我在'
