如何获取函数showEditionBlock()中标签元素的当前值并将它们设置为相应的输入字段？该函数将显示“编辑”div，但输入未获得标签的原始值。

<head>
        <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js"></script>

<script>
$(document).ready(
    function()
        {

           $("#companyNameText").keyup(
           function()
           {
               $("#companyNameLabel").html(this.value);
           });

           $("#companyCountryText").keyup(
           function()
           {
               $("#companyCountryLabel").html(this.value);
           });
    });
function showEditionBlock(){
    //$("div#edit").css('display','block').fadeIn("slow");  
    $("div#edit").fadeIn('slow', function(){ 
            $(this).css('display', 'inline'); 
        }); 
    }

function hideEditionBlock(){
    //$("div#edit").css('display','block').fadeIn("slow");  
    $("div#edit").fadeOut('slow', function(){ 
            $(this).css('display', 'none'); 
        }); 
    }



</script>
        <body>
                <div id="preview">
            <fieldset>
                        <label id="companyNameLabel" class="workExperience">
                                This is my company
                        </label>
                        <label id="companyCountryLabel" class="workExperience">
                                This is my company Country
                        </label>
                        <input type="button" value="edit" onclick="showEditionBlock();"/>

                        <input type="button" value="Ok" onclick="hideEditionBlock();"/>
            </fieldset>

您应该将innerHTML标签分配给输入的value。在普通的'Javascript中你可以做类似的事情：

document.getElementById("companyNameText").value =
    document.getElementById("companyNameLabel").innerHTML;
document.getElementById("companyCountryText").value =
    document.getElementById("companyCountryLabel").innerHTML;

使用jQuery，这是相同的：

$("#companyNameText").val($("#companyNameLabel").html());
$("#companyCountryText").val($("#companyCountryLabel").html());

将输入字段设置为标签元素的当前值
