Document. Body. appendchild () causes IE to terminate the operation

When I wrote JS today, I suddenly found that my test page was good under ff, but when I opened it with IE, I always showed the error "ie cannot open XXX page, ended operation, later I found thatProgramThe document. Body. appendchild () Statement is at fault. The implementation mechanism in FF is that the body element already exists when the page has not been fully read, and IE exists only when the page completely reads the end Body element, therefore, an error occurs when you insert the preceding statement to the page in IE. The solution is also very simple. One way is to put this statement into the window. the second method is to use setTimeout for delayed asynchronous calls. Another method is to put the statement after the </body> label.
