- 这个提交按钮和后面的cltr+enter键怎么不能发布消息到Textarea？
-
代码如下： <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>71-留言发布框</title> <script> window.onload=function () { var oBtn=document.getElementById('btn1'); var oTxt1=document.getElementById('txt1'); var oTxt2=document.getElementById('txt2'); oBtn.onclick=function(){ oTxt2.vaule+=oTxt1.vaule+'\n'; oTxt1.value=''; }; /* oTxt1.onkeydown=function (ev) { var oEvent=ev||event; if(oEvent.keyCode==13&&oEvent.ctrlKey) { oTxt2.vaule+=oTxt1.vaule+'\n'; oTxt1.value=''; } };*/ }; </script> </head> <body> <input id="txt1" type="text"> <input id="btn1" type="button" value="发布"><br/><br> <textarea name="发布信息" id="txt2" cols="30" rows="10"></textarea> </body> </html>
value都拼错了。。vaule==》value
window.onload = function () {
var oBtn = document.getElementById('btn1');
var oTxt1 = document.getElementById('txt1');
var oTxt2 = document.getElementById('txt2');
oBtn.onclick = function () {
oTxt2.value += oTxt1.value + '\n';///////
oTxt1.value = '';
};
oTxt1.onkeydown = function (ev) {
var oEvent = ev || event;
if (oEvent.keyCode == 13 && oEvent.ctrlKey) {
oTxt2.value += oTxt1.value + '\n';////////////
oTxt1.value = '';
}
};
}
