Solve the doubts about the onPropertyChange event in IE HTML! _html/css_WEB-ITnose

IE HTML onPropertyChange compatibility issues

The HTML document is as follows:














As shown in the above document, you will find that the onPropertyChange event is intermittently unable to respond during the input process. Currently, two solutions have been tried to ensure that the event is responded to every input:
1. Remove the V.value=V.value assignment. statement, modify the value of the input box, and the alert box will pop up every time, and the onpropertyChange event will respond every time the attribute is modified; but the reason why I respond to this event is to retrieve the value of V.value and then reassign it, so this solution cannot Take;
2. Remove the ..> tag. This method can ensure that even after the value of V.value is modified in the response function of the onPropertyChange event, the onPropertyChange event can respond every time; But after removing the ..> tag, the compatibility with div layout is very poor;

So I would like to ask the experts here! To retain the ..> tag (for layout compatibility), and the value of V.value may be modified in the response function of the onPropertyChange event (business needs), how to achieve this? ? ?
Could anyone please explain why this happens? ! ! ! ! ! ! ! ! !
Thanks! ! !

Is there any master? ? ?

In order to let Others can switch the input method, but block some special characters, etc., and sometimes the value will be changed by js. Using the oninput event is not supported by IE, and onkeyup and onkeydown cannot meet business needs! ! !

Moreover, I have used onmouseup and onkeyup in combination, but when I switch to the Simplified Chinese input method (Sogou), after inputting pinyin, the Chinese characters are not generated by clicking the space bar, but are displayed using the mouse click input method. The phrases that come out, such onmouseup and onkeyup cannot meet the needs, so I think it is best to monitor the changes in value, so use the onPropertyChange event!
