Is not a function solution

Note the reason:

The attachEvent method of the window object is only valid in the IE browser. Other browsers do not support this method, so an error is reported.

is not a function is actually the previous code, which is not compatible with Chrome and Firefox browsers.

("onblur",function(){="none"})

The above code will definitely report an error in the chrome browser.

Because the chrome browser binding event does not support attachment but supports addEventListener.

Here is a temporary solution:

if(!){
		("onblur",function(){="none"})
	}

But the effect will be lost, this will not report an error but the effect will be gone.

IE：(”onclick”, func);。
FF：(”click”, func, true)。
General: =func. Although both can use onclick events, the effects of onclick and the above two methods are different. Onclick only executes one process, while attachEvent and addEventListener execute a list of procedures, that is, multiple processes. For example: ("onclick", func1); ("onclick", func2) In this way, both func1 and func2 are executed.
