如何使用另一个.js文件中的函数？

Question

Here is the simplified of my code:

// script1.js
$(document).ready(function(){
    .
    .
    function myfunc(){ ... }
    .
    .
});


// script2.js
$(document).ready(function(){
    .
    .
    //doesn't work
    $.getScript("./script1.js");
    // anyway I need to call myfunc() here ... how can I access it?
    .
    .
});

As you can see, I've used $.getScript() to require sccript1.js file, but still myfunc() is not defined there. How can I handle that?

myfunc is defined inside a document.ready event and is not exposed globally , hence you are not able to use the same in another function which is not inside this document ready event .

You need to either export this function globally or define it outside document.ready event .

Export function globally

$(document).ready(function(){
    .
    .
    function myfunc(){ ... }
    window.myfunc = myfunc; //this line added here
    .
    .
});

Or define it outside

$(document).ready(function(){
    .
    .

    .
    .
});
function myfunc(){ ... }

try:

var myfunc=null;
// script1.js
$(document).ready(function(){
    .
    .
    myfunc = function (){ ... }
    .
    .
});


// script2.js
$(document).ready(function(){
    .
    .
myfunc();
.
});

Answer 3

//util.js

var test = (function (){
return {
myfunc : function (){ ... }
}
})();

// script1.js

$(document).ready(function(){
  test.myfunc();
});

// script2.js

$(document).ready(function(){
   // $.getScript("./script1.js");
   test.myfunc()
});

in your html you should put this order

<script src="util.js"></script>
<script src="script1.js"></script>
<script src="script2.js"></script>

Try to using absolute path. For example https://example.com/js/script1.js instead ./script1.js
