Javascript 当元素有值时,标签在页面加载时不浮动

Javascript 当元素有值时,标签在页面加载时不浮动,javascript,jquery,Javascript,Jquery,我有一个浮动标签脚本。该脚本工作正常,除非从php中提取值,加载页面时,值和标签重叠并相互重叠。这是我的html: <div class="top-row"> <div class="field-wrap"> <div class="controls"> <input type="text" class="floatLabel" name="property_address" value="<?php echo $addre

我有一个浮动标签脚本。该脚本工作正常,除非从php中提取值,加载页面时,值和标签重叠并相互重叠。这是我的html:

<div class="top-row">
  <div class="field-wrap">
    <div class="controls">
      <input type="text" class="floatLabel" name="property_address" value="<?php echo $address?>" required>
      <label for="property_address">Street Address</label>
    </div>
  </div>
  <div class="field-wrap">
    <div class="controls">
      <input type="text" class="floatLabel" name="property_city" value="<?php echo $city?>" required>
      <label for="property_city">City</label>
    </div>
  </div>
</div>
这是我的css:

.controls label.active {
    top: -15px;
    color: #555;
    background-color: white;
}

.controls label {
    position: absolute;
    left: 10px;
    top: 7px;
    color: #999;
    font-size: 18px;
    display: inline-block;
    padding-left: 5px;
    padding-right: 5px;
    margin: 0;
    font-weight: 400;
    background-color: rgba(255, 255, 255, 0);
    pointer-events: none;
    -moz-transition: color 0.3s, top 0.3s, background-color 0.8s;
    -o-transition: color 0.3s, top 0.3s, background-color 0.8s;
    -webkit-transition: color 0.3s, top 0.3s, background-color 0.8s;
    transition: color 0.3s, top 0.3s, background-color 0.8s;
}

您需要检查页面加载时是否浮动,因为可能有数据从服务器放置在字段中

作用${ 变量$fields=$.floatLabel; //输入数据时。。。 $fields.oninput,floatLabel; //文档加载后立即检查文本字段,以查找 //可能是在装载时添加的 浮动标签; 函数浮动标签{ $fields.eachfunction i,f{ 变量$field=$f; 如果$field.val.trim==| |$field.val==空白{ $field.next.removeClassactive; }否则{ $field.next.addClassactive; } }; } }jQuery; .controls.label.active{ 位置:相对位置; 顶部:-50px; 左:-175px; 颜色:555; 背景色:白色; } .控件标签{ 位置:相对位置; 顶部:0px; 左:-175px; 颜色:999; 字号:18px; 显示:内联块; 左侧填充:5px; 右侧填充:5px; 保证金:0; 字体大小:400; 背景色:rgba255、255、255、0; 指针事件:无; 过渡色:颜色0.3s,顶部0.3s,背景色0.8s; }
请包括CSS。嗨,我刚刚做了。谢谢。@ubuntujavy我对你的CSS做了一些调整,以获得正确的位置。查看更新的答案。酷!谢谢,斯科特。
