jQuery Value Help

I'm having problems getting the value of the input field.

function Send(id){ 
var send_to=$("#id").val(); 
$.post("send.php", { id:id }, function(data) { if(data==="OK"){  } else { } }); 
} 

Below is an example of the page.

<input type=text id=4543><button onclick=Send(4543);>SEND</button>
<input type=text id=8643><button onclick=Send(8643);>SEND</button>
<input type=text id=8645><button onclick=Send(8645);>SEND&l开发者_开发问答t;/button>
<input type=text id=2421><button onclick=Send(2421);>SEND</button>

I need to get the value of the input control whose id is passed to the send method.

Thank you! :)

If I understood correctly, then:

var send_to=$("#id").val();  

should be

var send_to=$("#" + id).val();

First of all your id's are invalid(not in HTML5).

Also bind the handler in document ready function

<input type=text id="txt4543"><button class="btn">SEND</button>
<input type=text id="txt8643"><button class="btn">SEND</button>
<input type=text id="txt8645"><button class="btn">SEND</button>
<input type=text id="txt2421"><button class="btn">SEND</button>


$(function(){
    $(".btn").click(function(){
        var txtElem = $(this).prev();
        var value = txtElem.val();
        $.post("send.php", { id:txtElem.attr("id") }, function(data) { if(data==="OK"){  } else { } });
    });
});
