是否可以使用jquery / javascript将doc / docx转换为html？(Is it possible to convert doc/docx to html using jquery/javascript? [closed])

 您可以将每个设置nil ： 
 
for index in 0 ..< roomsLiveStates.count {
    roomsLiveStates[index] = nil
}
 
 正如Swift编程语言在其控制流讨论中所说for语法： 
 
 
 
 这个例子打印五个表中的前几个条目： 
 
 
for index in 1...5 {
    println("\(index) times 5 is \(index * 5)")
}
 
 
 ...在上面的例子中， index是一个常量，其值在循环的每次迭代开始时自动设置。 因此，它不必在使用之前进行声明。 它只是通过包含在循环声明中隐式声明，而不需要let声明关键字。 
 
 
 正如这说的那样， index是一个常数。 因此，你不能改变它的价值。 

You can just set each to nil:
 
for index in 0 ..< roomsLiveStates.count {
    roomsLiveStates[index] = nil
}
 
As The Swift Programming Language says in its Control Flow discussion of for syntax:
 
 
 
This example prints the first few entries in the five-times-table:
 
 
for index in 1...5 {
    println("\(index) times 5 is \(index * 5)")
}
 
 
... In the example above, index is a constant whose value is automatically set at the start of each iteration of the loop. As such, it does not have to be declared before it is used. It is implicitly declared simply by its inclusion in the loop declaration, without the need for a let declaration keyword.
 
 
As this says, the index is a constant. As such, you can not change its value.
