将textarea内容发送到javascript函数

[英]Send textarea content to javascript function

Ok so I got a textarea and a link (which works as a button) and what I am trying to do is that when I click on the link, it sends the content from the textarea to a javascript function. 好的,我得到了一个textarea和一个链接(用作按钮),而我想做的是,当我单击链接时,它将内容从textarea发送到javascript函数。 Something like this...: 像这样...:

<textarea name="text" placeholder="Type your text here!"></textarea>
<a href="" onclick="myFunction(<!-- sends the value of the textarea that the user enters and then sends it to myFunction -->); return false;">Send!</a>

Just assign an id to your textarea, and use document.getElementById : 只需为您的textarea分配一个id ,然后使用document.getElementById

<textarea name="text" placeholder="Type your text here!" id="myTextarea"></textarea>
<a href="" onclick="myFunction(document.getElementById('myTextarea').value); return false;">Send!</a>

Alternatively, you could instead change your myFunction function, to make it define the value inside the function: 或者,您可以改为更改myFunction函数,以使其定义函数内部的值:

JS: JS:

function myFunction() {
    var value = document.getElementById('myTextarea').value;
    //rest of the code
}

HTML: HTML:

<textarea name="text" placeholder="Type your text here!" id="myTextarea"></textarea>
<a href="" onclick="myFunction(); return false;">Send!</a>

And if you're using jQuery, which it does look like you do, you could change the document.getElementById('myTextarea').value to $('#myTextarea').val(); 而且,如果您使用的是jQuery(确实如此),则可以将document.getElementById('myTextarea').value更改$('#myTextarea').val(); to get the following: 得到以下内容:

JS: JS:

function myFunction() {
    var value = $('#myTextarea').val();
    //rest of the code
}

HTML: HTML:

<textarea name="text" placeholder="Type your text here!" id="myTextarea"></textarea>
<a href="" onclick="myFunction(); return false;">Send!</a>

you can do simply like this to achieve it, just call function and do all work in that function: 您可以像这样简单地实现它,只需调用函数并在该函数中完成所有工作:

<a href="" onclick="myFunction();">Send</a>

Jquery code: jQuery代码:

function myFunction()
{
    var text = $('textarea[name="text"]').val();

    // use text here

    return false;
}
