HTML5-Copy the code in the book but the function cannot be executed and parsed (uncaught referenceerror:xxx is not defined)

In the JS file to write a method to pass parameters:

Moveelement (Id,name,price)

{

Alert ("ID:" +id+ "Name:" +name+ "Price:" +price ");

}

Pass-through Value method:

<p onclick= "moveelement (elementid,222,11)" >gogo</p>;

But the name (string) can not be passed, only the number. <p onclick= "moveelement (444,222,11)" >gogo</p>;

Later found to escape the string, and later changed to write as follows:

<p onclick= "moveelement ( \"" +elementID+ "\" , 222,11)" >gogo</p>;
