[英]Hide Label When input is in focus
I am having a form with label overlaying the input. 我有一个标签覆盖输入的表单。 Like in the below image
如下图所示
Below is a code example of the same. 下面是相同的代码示例。
<label for="edit-submitted-name--2">
Name
<span class="form-required" title="This field is required.">*</span>
</label>
<input id="edit-submitted-name--2" class="form-text required" type="text" maxlength="128" size="35" value="" name="submitted[name]">
I want to use jquery and hide the label each time a user focus on the input. 我想使用jquery并在每次用户关注输入时隐藏标签。 Label should only be visible if the input is empty or if the input is not in focus.
仅当输入为空或输入未处于焦点时,才应显示标签。
$("input").focus(function () {
//hide the label corresponding to this input
});
How do i select the label corresponding to this input using jquery? 如何使用jquery选择与此输入对应的标签?
Note: I cant change anything much in the html as its generated by a module in Drupal. 注意:我不能在html中更改任何内容,因为它是由Drupal中的模块生成的。
placeholder attribute is the right tool for this job: 占位符属性是此作业的正确工具:
<input id="edit-submitted-name--2" class="form-text required" type="text" maxlength="128" size="35" placeholder="Name *" name="submitted[name]">

But don't forget that label-less input fields are bad practice. 但不要忘记,无标签输入字段是不好的做法。 Placeholders should be treated like a hint.
占位符应该被视为提示。 They are not a replacement for labels.
它们不是标签的替代品。
Select the previous element from the current element. 从当前元素中选择前一个元素。
$(this).prev("label").hide();
and 和
$(this).prev("label").show();
However, this isn't the purpose of the label element. 但是,这不是标签元素的目的。
