fireEvent

--- < form> < textarea onkeypress =" foo（this，event）">< / textarea> < input type =" button"值= QUOT;栏（）" onclick =" bar（）"> < / form> < script type =" text / javascript"> 函数foo（elem，evt）{ alert（ [ " elem：" + elem .nodeName， " shiftKey：" + evt.shiftKey， " keyCode：" + evt.keyCode ]。加入（" \ n"） ）; } 功能栏（）{ if（document.createEventObject）{ var evt = document.createEventObject（）; evt.shiftKey = true; evt .keyCode = 121; document.forms [0] .elements [0] .fireEvent（" onkeypress"，evt）; } } < / script> --- HTH， 是的。 You seem to be targeting IE only, so the solution will be IE only. Notethat triggering a keypress event does not deal with the built-inpre-event mechanics, i.e. you won''t see any letter in your textarea. Asfor manipulating the textarea''s value, use IE ranges. Though the idea of triggering events is a good one, I believe that thereusually are better approaches, using handlers and "proxies", but notknowing what you want to do makes it difficult to determine the best one:-)---<form><textarea onkeypress="foo(this, event)"></textarea><input type="button" value="bar()" onclick="bar()"></form> <script type="text/javascript">function foo(elem, evt){alert(["elem : " + elem.nodeName,"shiftKey : " + evt.shiftKey,"keyCode : " + evt.keyCode].join("\n"));} function bar(){if(document.createEventObject) {var evt=document.createEventObject();evt.shiftKey=true;evt.keyCode=121;document.forms[0].elements[0].fireEvent("onkeypress", evt);}}</script>---HTH,Yep. 您似乎只针对IE，因此该解决方案仅限IE。注意触发按键事件不会处理内置的事件前机制，即你在textarea中看不到任何字母。为了操纵textarea的值，使用IE范围。 虽然触发事件的想法很好，但我相信那里通常是更好的方法，使用处理程序和代理，但不知道你想做什么使得很难确定最好的一个： - ） You seem to be targeting IE only, so the solution will be IE only.

While I was reading some more on this subject I also noticedthere''s method called ''handleEvent()''. What''s the difference betweenfireEvent and handleEvent? --,_,(O,O)( )---"-"-alex 这篇关于fireEvent的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
