Question

我正在为我的软件编写一个ajax实时搜索功能。有多个输入需要在每个表单上搜索ajax。一切都很好，除了我希望结果列表显示在悬停＆＃34; p＆＃34;我正在搜索的输入正下方的元素。现在我有一个＆＃34; p＆＃34; with class =＆＃34; options＆＃34;在每个输入下方以显示结果。当我输入时，结果显示在每个＆＃34; p＆＃34;中，即悬停在每个输入下。有没有办法只引用当前输入的子节点，还是我需要使用一个单独的函数显式引用每个输入所需的

？我在互联网上尝试了很多子选择器选项，但没有一个能够工作。代码如下。谢谢你的建议。

$(document).ready(function() {

//sets the chosen value into the input
$( ".options").on( "click", function(event) {
   var item =  $(event.target).text(); 
   $('#acctname').val(item);//place chosed result into the acctname input
   $('.options').hide();//hide result options after click
}); 

//On pressing a key in input field, this function will be called.
$(".textinput").keyup(function() {
   var id = $(this).attr("id");
   var val = $(this).val();
   if (val === '') { //Validating, if "name" is empty.
   $('div > p').html('').show();
   }else {//If input is not empty.

        $.ajax({
           type: "POST",
           url: "../model/ajax/livesearch.php",
           data: {id: id, val: val},
           success: function(html) {//place the result into the p element and set the proper css
              $('div > p').html(html).show().css({"position":"absolute","z-index":"+1","cursor":"pointer","color":"black","background-color":"white"});
              }
       });
   }
});
});

更新：这就是我的HTML表单的结构。

<form action= "../model/dataentry.php?formname=enter_deposit" method="POST" id="ajaxform" name="ajaxform">
<div class = "label"><p1>Revenue Account Name</p1></div><div class = "field"><input class = "textinput" type="input" name="acctname" id="acctname" value = ""  autocomplete="off">
<p class = "options"></p></div>
<div class = "label"><p1>Revenue Account Number</p1></div><div class = "field"><input class = "textinput" type="input" name="acctno" id="acctno" value = ""  autocomplete="off">
<p class = "options"></p></div>
<input class = "submit" name = "Submit" type = "button" id = "ajaxsubmit" value = "Submit"  >
<input class = "submit" name = "Close" type = "button" id = "close" value = "Close"  >
</div>
</form>

如果有人好奇，我找到了解决问题的方法。通过为每个div分配类＆＃34;选项＆＃34;一个id等于其父亲的身份加上＆＃34; _opt＆＃34; （即＆＃34; acctname＆＃34;输入将有一个带有id＆＃34; acctname_opt＆＃34;）的子div，我可以在我的函数中动态编辑div id，将结果列表放在我想要的位置。这是我的新javascript代码。工作完美无瑕。感谢大家的帮助。

$(document).ready(function() {

//sets the chosen value into the input
$( ".options").on( "click", function(event) {
   var item =  $(event.target).text(); 
   var clickedid = $(this).attr('id'); 
   var targetid = clickedid.split('_'); //remove the '_opt' suffice to get the target id
   $('#' + targetid).val(item);//place chosed result into the acctname input
   $('.options').hide();//hide result options after click
}); 

//On pressing a key in input field, this function will be called.
$(".textinput").keyup(function() {
   var id = $(this).attr("id");
   var optid = id + '_opt'; //set the target element id
   var val = $(this).val();
   if (val === '') { //Validating, if "name" is empty.
   $('#' + optid).html('').show();
   }else {//If input is not empty.
        $.ajax({
           type: "POST",
           url: "../model/ajax/livesearch.php",
           data: {id: id, val: val},
           success: function(html) {//place the result into the p element and set the proper css
              $('#' + optid).html(html).show().css({"position":"absolute","z-index":"+1","cursor":"pointer","color":"black","background-color":"white"});
              }
       });
   }
});
});
