jquery，当字段失去焦点时提交表单 [英] jquery, submit form when field loses focus

问题描述

如果字段（在这种情况下表单只有一个字段）失去焦点，我该如何提交表单？

我试过这个，但它不起作用：

  $（form）。submit（）; 
  

更新

<我忘了提到表单也是用jquery创建的：

  $（div）。html（' < form action =javascript：void（0）style =display：inline;>< input type =textvalue ='+ oldValue +'>< / form>'）; 
  

这可能就是为什么它不会提交，我认为这是因为没有观察到事件。

解决方案

触发表单的提交（）事件。您可以通过附加 blur（） 事件处理程序。

  $（＃field）。blur（function（）{
 $（＃form）。submit（）; 
}）; 
  

如果您的字段没有ID或其他方便识别它（我建议你也可以做这样的事情：

  $（＃form：input）。blur（function（）{
 $（＃form）。submit（）; 
}）; 
  

因为只有一个字段。

How can I submit a form when a field (In this case the form only has one field) loses focus?

I tried this, but it's not working:

$("form").submit();

UPDATE

I forgot to mention that the form was created with jquery as well:

$("div").html('<form action="javascript:void(0)" style="display:inline;"><input type="text" value="' + oldValue + '"></form>');

This is probably why it won't submit, I think it's because the events aren't being observed.

解决方案

Trigger the form's submit() event when the field loses focus. You can detect this by attaching a blur() event handler to it.

$("#field").blur(function() {
  $("#form").submit();
});

If you field doesn't have an ID or other means of easily identifying it (which I would recommend) you could also do something like this:

$("#form :input").blur(function() {
  $("#form").submit();
});

since there's only one field.
