jQuery .click（）仅在加载时触发

Question

I've searched on here plenty of places and I have not been able to find my situation, so here goes.

I am trying to avoid using the html inline onclick, so in doing so I am using the jquery click() like so

$(document).ready(function(){
    $("#start").click(game());
});

When I use this, the function game() runs automatically and only runs and load time.

If I use the inline onclick, it works only when I click, and it works every time I click. Why is this?

Edit.. I swear I tried that.. oh well, It worked!!!

Answer 1

You are calling the game() function and passing its result to .click() . Since its result is (presumably) not a function you have not actually set up a click handler at all. You need to pass a reference to the function, so remove the parentheses:

$("#start").click(game);

Answer 2

You are executing game() immediately by adding the parenthesis. If you want game to be evaluated on click then you need

$(document).ready(function(){
    $("#start").click(game);
});

Answer 3

您需要将其更改为：

$("#start").click(game);

Answer 4

Always more advisable to use .on & an anonymous function since it takes confusions like these out of the picture;

$(document).ready(function() {
        $('#start').on('click', function () {
            game();
        });
    }
);

What you're doing would be similar to

$(document).ready(function() {
        $('#start').on('click', function () {
            game();
        }());
    }
);

Answer 5

Maybe youe need define game this way:

var game = function(e,...)

$("#start").click(game);

And remember the first parameter is the event object, passed from click function.

You could use a jquery function in a html element.

<canvas id="game" onclick="jqueryFunction()"></canvas>

In the jqueryFunction() make a if else statement so if game is running : fire.

else if game not running :load game.
