javascript - jQuery 选择器 - 仅向选定的 id 插入值

Question

我的表单有很多输入。在 JavaScript 中，我有用于打开模式窗口并选择选项的脚本。

$("input[id^='field'][id$='A']").on('click', function() {
    $("#bg").fadeIn(400, function() {
        $("#modal").fadeIn(400);
    });
});

$("#modal img").on('click', function() {
    var text = $(this).siblings('.descr').text();
    $("#modal").fadeOut(400, function() {
        $("#bg").fadeOut(400, function() {
            $("input[id^='field'][id$='A']").val(text);    
        });
    });
});

(片段中的完整代码)

如何编辑此选择器，仅将所选值插入到我单击的输入中？

input[id^='field'][id$='A']  

每个 ID 都是唯一的。

$("input[id^='field'][id$='A']").on('click', function() {
    $("#bg").fadeIn(400, function() {
        $("#modal").fadeIn(400);
    });
});

$("#modal img").on('click', function() {
    var text = $(this).siblings('.descr').text();
    $("#modal").fadeOut(400, function() {
        $("#bg").fadeOut(400, function() {
            $("input[id^='field'][id$='A']").val(text);    
        });
    });
});

$("input[id^='field'][id$='B']").on('click', function() {
    $("#bgB").fadeIn(400, function() {
        $("#modalB").fadeIn(400);
    });
});

$("#modalB img").on('click', function() {
    var text = $(this).siblings('.descr').text();
    $("#modalB").fadeOut(400, function() {
        $("#bgB").fadeOut(400, function() {
            $("input[id^='field'][id$='B']").val(text);    
        });
    });
});

.field {margin: 10px;}
#bg {position: fixed; height: 100%; width: 100%; background: rgba(0,0,0,0.5); left: 0; top: 0; display: none;}
#modal {position: absolute; height: 300px; width: 600px; top: 50%; left: 50%; margin-top: -150px; margin-left: -300px; background: #fff; display: none;}
#modal div {display: inline-block;}
#modal img {height; 180px; width: 180px; opacity: 0.8; cursor: pointer; }
#modal img:hover {opacity: 1;}

#bgB {position: fixed; height: 100%; width: 100%; background: rgba(0,0,0,0.5); left: 0; top: 0; display: none;}
#modalB {position: absolute; height: 300px; width: 600px; top: 50%; left: 50%; margin-top: -150px; margin-left: -300px; background: #fff; display: none;}
#modalB div {display: inline-block;}
#modalB img {height; 180px; width: 180px; opacity: 0.8; cursor: pointer; }
#modalB img:hover {opacity: 1;}

.descr {position: relative; width: 180px; padding: 0 0 0 70px ;}

您可以将 id 存储在变量中。打开模型后进行设置，并在设置值时使用它。

var inputAId = "";
$("input[id^='field'][id$='A']").on('click', function() {
  // Set it here...
  inputAId = this.id;
  $("#bg").fadeIn(400, function() {
    $("#modal").fadeIn(400);
  });
});

$("#modal img").on('click', function() {
  var text = $(this).siblings('.descr').text();
  $("#modal").fadeOut(400, function() {
    $("#bg").fadeOut(400, function() {
      // Later use it here...
      $("#" + inputAId).val(text);
    });
  });
});
