在边栏中,为表单显示两个<select>
选项。第二个<select>
取决于第一个的选择。第二个<select>
将通过Google Apps脚本调用适当的数组。
我无法通过事件监听器,尝试google.run
或引用其他函数来填充数组。
下面有三个<select>
字段。首先是主要的。第二个是依赖于第一个的传统数组。第三个<select>
是我无法从Apps Script服务器端代码获取提取数组的地方。请记住,我正在尝试根据第一个<select>
提取不同的数组。
//Google Apps Script
function Array1() {
var rng = SpreadsheetApp.getActiveSpreadsheet().getRangeByName('perTwo').getValues();
Logger.log(rng);
return rng;
}
function getValuesForRngActive(students_active) {
var rngValues = SpreadsheetApp.getActiveSpreadsheet().getRangeByName('students_active').getValues();
return rngValues.sort();
}

App Script函数应将范围名称作为参数:
function getValuesForRange(rangeName) {
var rngValues = SpreadsheetApp
.getActiveSpreadsheet()
.getRangeByName(rangeName)
.getValues();
return rngValues.sort();
}
以便可以将范围名称students_active
传递到App Script函数中
...,它的成功处理程序回调可能应该是populateSelectA()
。
google.script.run
.withSuccessHandler(populateSelectA)
.getValuesForRange('students_active');
上述代码还有其他一些问题...
这至少可以使您用<select>
填充一个<option>
。
以某种方式的误解是,这些回调函数仅接受一个参数,而您的populate()
接受两个... App脚本应返回{}
或[]
; function populateSelectA(data) {}
和function populateSelectB(data) {}
之类的JS函数声明。 jQuery也可以用于客户端脚本。
