在HTML中单击按钮时调用JavaScript函数

Question

I wrote a simple JavaScript code that allows people to enter a number and it should return either FizzBuzz, Fizz, Buzz or just the number if it did not meet the conditions of the FizzBuzz game. I then tried to create a button in HTML with the following code:

<button onclick="fBCalc(prompt("Enter a number!"))">FizzBuzz</button>

I have also tried this:

<input type="button" name="FizzBuzz" value="FizzBuzz" onClick="fBCalc(prompt("Enter a number!"))" />

Both methods did not work. I have searched Google for an answer but I have tried them and nothing happens when I click the button. I made sure that the function was called correctly. This works without the button so I do not know why it shouldn't work with a button. Unless a button is unable to prompt oo Does anyone know what is wrong?

Here is a pastebin to my full HTML code: http://pastebin.com/YPGdbTVQ

Answer 1

You haven't pasted your code properly here, but I did spy what I suspect is your issue on your Pastebin:

<button onclick="fBCalc(prompt("Enter a number!"))">FizzBuzz</button>

You can't put quotes inside of quotes the way you have here, because the browser can't figure out which ones do what. Try swapping the inner quotes with single-quotes:

 <button onclick="fBCalc(prompt('Enter a number!'))">FizzBuzz</button>

Coincidentally, good luck with your grades! ;)

Answer 2

您不能将双引号放在双引号内，因此使代码像这样

<button onclick="fBCalc(prompt('Enter a number!'))">FizzBuzz</button>
