刚学ajax,遇到一个奇怪的问题,textarea内容无法用javascript”打印“ - Web 开发 / Ajax
问题是这样的,我用ajax做一个发站内短信的东东,但是那个短信内容用始终显示不出来,在postNewMsg()函数中,能够检查到msgcontent是否填写了,如果没有填写,函数的alert能正常提示工作,但是getInfo( "message.asp?msg_action=postnewmsg&msgtouser= "+msgtouser.value+ "&msgtitle= "+msgtitle.value+ "&msgcontent= "+msgcontent.value+ " ");这句话中,msgcontent无法传递给message.asp(其他参数都传过去了)。后来我又加了一句测试的语句就是
document.getElementById( "my_main ").innerHTML   =msgcontent.value;这句话也死活不正常,如果是表单中的其他元素,上一句则能正常显示比如document.getElementById( "my_main ").innerHTML   =msgtouser.value;   就能显示你在表单中填写的收件人。我实在搞不懂为什么msgcontent不行,而其他表单元素就行啊??高人指点迷津啊!!!
