如何在切换到下一个输入文本后自动触发输入按钮(how to automatic trigger the enter button after switching to next input text)

你好我需要在用户切换到另一个html input type='text'后自动触发输入按钮。 我需要这样做，以便我可以验证表单。

这里是我的代码：

<input type="text" class="form-control input-sm" name="student_lastname" placeholder="Last Name" pattern="[A-Za-z].{1,}" title="Only Letters are accepted and more than 1 letter" required>

我需要错误title="Only Letters are accepted and more than 1 letter"弹出时，用户完成键入框

现在这是我的代码看起来像

hello guys i need to automatic trigger the enter button after the user switch to another html input type='text'. i need to do this so that i can validate the form.

onblur是完美的解决方案，专为用户离开输入字段时制定。 只要做这样的事情：

对于HTML：

<input type="text" onblur="validate()" />

对于JS：

function validate() { // This is how you automatically make them click the Enter button: enterButton.click(); }

onblur is the perfect solution, and was made specifically for when the user leaves an input field. Just do something like this:

For HTML:

<input type="text" onblur="validate()" />

And for JS:

function validate() { // This is how you automatically make them click the Enter button: enterButton.click(); }
