我正在尝试从隐藏字段中获取值。

这是由 Visualforce 页面 (Salesforce) 吐出的 HTML（ID 是动态生成的）

<div style="width:300px;position:relative" id="massConvertwithInputs:pbmconvertInput:pbformmconvertInput:pbsmconvertInput:pbspbtable:0:optableAccount">
<!--  Need value for below field to be alerted -->
<input type="hidden" value="001i0000008LDtv" id="massConvertwithInputs:pbmconvertInput:pbformmconvertInput:pbsmconvertInput:pbspbtable:0:accountLookup_lkid" name="massConvertwithInputs:pbmconvertInput:pbformmconvertInput:pbsmconvertInput:pbspbtable:0:accountLookup_lkid">

</select></div>

这是我正在使用警报值的 jquery 代码

<script>

$(document).ready(function () {

$('form :input[id$="accountLookup"]').change(function() {
     $('form :input[id$="accountLookup"]').each(function () {
            var str= $(this).attr("id") + "_lkid"; 
            alert($(str).val());// This alert shows undefined
            alert($(this).val());// This shows the Aethna Home Products which correct
            alert($('massConvertwithInputs:pbmconvertInput:pbformmconvertInput:pbsmconvertInput:pbspbtable:0:accountLookup_lkid').val());  // This shows undefined
});  
}); 
$('form :input[id$="accountLookup"]').change(function() {
     $('form :input[id$="accountLookup_lkid"]').each(function () {
            alert($(this).val());  // This shows a blank value
});  
}); 
});   


</script>

我需要获取该字段的值massConvertwithInputs:pbmconvertInput:pbformmconvertInput:pbsmconvertInput:pbspbtable:0:accountLookup_lkid

我已经用每个警报当前抛出的内容评论了 jquery 脚本

知道我在做什么错吗？

您错过了选择器中的 # ：

alert($("#massConvertwithInputs:pbmconvertInput:pbformmconvertInput:pbsmconvertInput:pbspbtable:0:accountLookup_lkid").val());

同样在这里

var str= '#' + $(this).attr("id") + "_lkid"; 
alert($(str).val());

使用 id 作为选择器时需要使用 #。如果是类，则. 用作选择器

$('massConvertwithInputs:pbmconvertInput:pbformmconvertInput:pbsmconvertInput:pbspbtable:0:accountLookup_lkid').val()

和

$('#massConvertwithInputs:pbmconvertInput:pbformmconvertInput:pbsmconvertInput:pbspbtable:0:accountLookup_lkid').val()
