This is a JavaScript Function to check if an element exists, I use it regularly in an If.
The function:
|
1 2 3 |
function element_exists (elem) { return((elem)?1:0); } |
The test:
|
1 2 3 4 5 6 7 8 9 10 11 12 |
//Test1 if(element_exists(document.getElementById("masthead"))){ console.log("element exists"); }else{ console.log("element not exists"); } //Test2 if(element_exists(document.getElementById("masthead1"))){ console.log("element exists"); }else{ console.log("element not exists"); } |
Our result:
|
1 2 |
element exists element not exists |
We could see it works as it should.
