jquery (document). Ready using document.write results in a page-blank solution

Do project to use the load mechanism to dynamically load JS, due to file dependencies, requires JS must be loaded one by one (that is, sync), file loading no problem, but found that there is a problem when in $ (document). Ready () Using the document.write form of load will result in page whitespace, view the DOM, and discover that it has been emptied.
After checking Google knows that because document.write only when the DOM is not ready for normal output, if the DOM ready after use will result in the re-output (that is, empty the document and write).

Solving method

Calling document.write when the DOM is not ready solves the problem.
