我很困惑我的追加()没有出现在HTML中。你能告诉我以下代码中的错误:
<div class="form-group" id="password">
<label class="control-label" for="inputError"> Password:</label>
<input type="password" class="form-control" id="input-password" placeholder="Password" value="" name="password"/>
</div>
我的js:
<script type="text/javascript">
$('input[name="password"]').focusout(function() {
if($(this).val()==""){
$('#password').attr('class','form-group has-error');
$('#password .control-label').prepend("<span class='fa fa-times-circle-o'></span>");
$('#password .control-label').text(' Input your new password!');
}
});
</script>
答案 0 :(得分:3)
假设触发了focusout事件,问题是你在.prepend()之后使用.text()将删除添加了.prepend()的内容
$('input[name="password"]').focusout(function () {
if ($(this).val() == "") {
$('#password').attr('class', 'form-group has-error');
$('#password .control-label').text(' Input your new password!');
$('#password .control-label').prepend("<span class='fa fa-times-circle-o'></span>");
}
});
演示:Fiddle
所以
jQuery(function($){
$('input[name="password"]').focusout(function () {
if ($(this).val() == "") {
$('#password').attr('class', 'form-group has-error');
$('#password .control-label').text(' Input your new password!').prepend("<span class='fa fa-times-circle-o'></span>");
//$('#password .control-label').html('<span class="fa fa-times-circle-o"></span> Input your new password!');
}
});
});
