I have the next in JS:
function doC() {
this.try = document.getElementById("try");
function tryC(){
//do something
}
}
Now, I want to call tryC function, when so I wrote the next:
<script type="text/javascript" src="myFile.js"></script>
<script type="text/javascript">tryC();</script>
But as I see, nothing happen. Ho I call tryC()?
You have defined C in the scope of doC. It is not accessible outside of doC.
If you want it to be accessible globally, then you have to explicitly assign it a global.
window.C = function () { /* etc */ };
Creating globals is usually a bad idea, more so when they aren't created at load time. There is probably a better way to achieve whatever problem you are trying to solve with this.
Your tryC is defined inside doC, it's not exposed (it's private), you can do:
function doC() {
this.try = document.getElementById("try");
return function(){
alert('Try C');
}
}
doC()(); // alerts
or
function doC() {
this.try = document.getElementById("try");
return {
tryC : function(){
alert('Try C');
}
}
}
doc().tryC(); //alerts
Or your way (globals all around)
function doC() {
this.try = document.getElementById("try");
this.tryC = function(){
alert('Try C');
}
}
doC(); // call first!
tryC(); // alerts
dois a keyword likeif, so you should rename that function.doCisn't a keyword, so it doesn't matter.
