输入按键时获取输入文本的值 [英] get the value of input text when enter key pressed

问题描述

我试过这个：

I am trying this:

<input type="text" placeholder="some text" class="search" onkeydown="search()"/>
<input type="text" placeholder="some text" class="search" onkeydown="search()"/>

用一些javascript检查是否按下回车键：

with some javascript to check whether the enter key is pressed:

function search() {
    if(event.keyCode == 13) {
        alert("should get the innerHTML or text value here);
    }
}

目前这工作正常，但我的问题如何获得文本字段内的值，我正在考虑将一个引用this传递给该函数，或者如果他们有id，那么我可以使用ID的，但是然后我看不出如何区分哪一个键入，将我的问题带回到同样的问题......

this works fine at the moment, but my question how to get the value inside the text field, I was thinking of passing a reference "this" to the function, or if they had id's then I could use ID's but then I don't see how I could differentiate between which one has been typed, bringing my back to the same problem again...

推荐答案

试试这个：

Try this:

<input type="text" placeholder="some text" class="search" onkeydown="search(this)"/>  
<input type="text" placeholder="some text" class="search" onkeydown="search(this)"/>

JS代码

JS Code

function search(ele) {
    if(event.key === 'Enter') {
        alert(ele.value);        
    }
}
