如何使用已选中的复选框值创建数组?
注意:(重要)我需要像[1,2,3,4,5]这样的数组,而不是像["1","2","3","4","5"]那样的数组.
注意:大约有50个复选框.
有人能帮我吗?请!
谢谢!
我似乎无法摆脱这个错误。
我试过删除package-lock.json
&node_modules
后跟npm install
,但是,它不起作用。

我对何时使用deferred.resolve()
和感到非常困惑deferred.reject()
。
快速范例
var doSomething = function() {
var deferred = $.Deferred();
if ( typeof myVar === "object" ) {
// Do something with myVar - Start.
deferred.resolve();
// Do something with myVar - End.
} else {
// myVar isn't an object, but the function has finished executing
// and that's what I want to know.
// With reject() I'll be forced to use always() instead of done()
// because there'll be also a fail() method …
