Question

嗨，其实我正在研究jQuery。在这里，我编写了更新项目名称的代码。为此，我给了一个输入字段＆amp;保存按钮。我正在获取项目名称并将其显示在输入字段中。编辑输入字段后，当我单击保存按钮时，项目名称将替换为输入字段中的任何名称。所以，我在这里更新价值时遇到问题。请帮我。提前致谢。

$(document).ready(function() {
  $(".detail-wrp").on("click", function() {
    let inputVal = $(".prjt-nme", this).text();
    $(".prjt-nme", this).hide();
    $(".update-wrp", this).show();
    $(".detail-input", this).val(inputVal).focus().select();
    return false;
  });
  $(".detail-save-btn").on("click", function() {
    $(".prjt-nme").css({
      "display": "block"
    });
    $(".update-wrp").css({
      "display": "none"
    });
    let pk = $(this).parents(".detail-wrp").find(".detail-input").val();
    $(this).parents(".detail-wrp").find(".prjt-nme").text(pk);
  });
});

.general-settings>div {
  display: flex;
  padding: 6px 10px 6px 10px;
  width: 100%;
  cursor: pointer;
}

.general-settings>div:first-child {
  padding-top: 10px;
}

.general-settings>div:hover {
  background: #e9e9e9;
}

.general-settings>div:hover .prjt-edit-icon {
  display: block;
}

.general-settings>div>div:first-child {
  width: 40%;
}

.general-settings>div>div:last-child {
  width: 60%;
}

.general-settings>div>div .prjt-nme a {
  display: none;
}

.general-settings>div>div .prjt-nme a i {
  margin-top: 2px;
  margin-right: 10px;
}

.general-settings .update-wrp {
  display: none;
}

Answer 1

按以下方式更新您的编辑点击：

    $(".prjt-nme").on("click", function() {
    let inputVal = $(this).text();
    $(this).hide();
    $(this).next().show();
    $(".detail-input", this).val(inputVal).focus().select();
    return false;
    });

此外，您需要将项目名称放在<span>中并更新您的保存功能以再次显示铅笔图标。

<div class="prjt-nme"><span>abcdefgh.comA1</span> <a href="#" class="float-right prjt-edit-icon"><i class="fas fa-pencil-alt"></i></a></div> //html 

$(this).parents(".detail-wrp").find(".prjt-nme > span").html(pk); //in save function

Answer 2

$(".update-wrp", this).show();

对此进行评论。 .show（）命令将继续显示它，除非您提供另一个代码来从中取消焦点。您可以输入几个.focus来控制它，或者更好地将它注释掉并再次测试
