提交表单的时候,不是使用ajax提交,就是传统的表单提交,为防止表单重复提交,应该怎么写javascript或jquery代码呢?如果提交没成功,怎么恢复提交按钮?
html如下:
<form>
<fieldset class="form-group">
<label for="exampleInputEmail1">Email address</label>
<input type="email" class="form-control" id="exampleInputEmail1" placeholder="Enter email">
<small class="text-muted">We'll never share your email with anyone else.</small>
</fieldset>
<fieldset class="form-group">
<label for="exampleInputPassword1">Password</label>
<input type="password" class="form-control" id="exampleInputPassword1" placeholder="Password">
</fieldset>
<fieldset class="form-group">
<label for="exampleSelect1">Example select</label>
<select class="form-control" id="exampleSelect1">
<option>1</option>
<option>2</option>
<option>3</option>
<option>4</option>
<option>5</option>
</select>
</fieldset>
<fieldset class="form-group">
<label for="exampleSelect2">Example multiple select</label>
<select multiple class="form-control" id="exampleSelect2">
<option>1</option>
<option>2</option>
<option>3</option>
<option>4</option>
<option>5</option>
</select>
</fieldset>
<fieldset class="form-group">

</fieldset>
<fieldset class="form-group">
<label for="exampleInputFile">File input</label>
<input type="file" class="form-control-file" id="exampleInputFile">
<small class="text-muted">This is some placeholder block-level help text for the above input. It's a bit lighter and easily wraps to a new line.</small>
</fieldset>
<div class="radio">
<label>
<input type="radio" name="optionsRadios" id="optionsRadios1" value="option1" checked>
Option one is this and that—be sure to include why it's great
</label>
</div>
<div class="radio">
<label>
<input type="radio" name="optionsRadios" id="optionsRadios2" value="option2">
Option two can be something else and selecting it will deselect option one
</label>
</div>
<div class="radio disabled">
<label>
<input type="radio" name="optionsRadios" id="optionsRadios3" value="option3" disabled>
Option three is disabled
</label>
