Method for calling binary element in Javascript

The invention provides a method for calling a binary element in a Javascript. The method comprises the following steps that: a Javascript engine obtains a character string in a Javascript sentence, and judges whether the character string is a is a Javascript language node or not; if the character string is not the Javascript language node, an exception interceptor of the Javascript engine intercepts and obtains the character string; whether the binary element corresponding to the character string exists or not is inquired in a loading path of the binary element; and a binary element object corresponding to the character string is created and is encapsulated into a Javascript object. The method achieves the effect of flexibly loading the binary element according to requirements in the Javascript parsing execution process.
