Question

我已经创建了一个表单，但是只有按下按钮提交才会提交...如果按下Enter键，如何提交？这是我的表格代码：

<form method="POST" id="form01">
<textarea name="inputBox123" id="myTextarea" style="white-space:nowrap;">
</textarea>
<input type="button" value="Submeter" onclick="myFunction()" />
</form>

<script type="text/javascript">

function myFunction(val) {

var testThis = document.getElementById("myTextarea").value;

if ( testThis.indexOf("launch") > -1 ) {
window.location = 'http://www.cateto.weebly.com/benoit.html';
return false;


}

}
</script>

谢谢，

汤姆

Answer 1

使用Ref发送表单，而不是使用<input type="button" />。

输入按钮应默认提交表单。

您应该将事件监听器附加到org.springframework.web.util.NestedServletException: Request processing failed; nested exception is java.lang.IllegalArgumentException: Header value must not be null at

Enter

＆＃13;

var textarea = document.querySelector("textarea");//get textarea tag
//NOW replace this with: var input = document.getElementById("myTextarea")

//BELOW change textarea with input
textarea.addEventListener("keypress", function(e){
  console.log(e.which, e.target.value);
  if(e.which === 13)//code number for enter key
    myFunction(e.target.value);//run function with value
