Question

然而，当我将其更改为formperper语法时，Jquery不会重新启用已禁用的保存功能。如何在给定此函数的情况下删除此属性

<div id="newArticleForm">
    <?php
    echo $this->Form->create('Post', array('action' => 'add'));
    echo $this->Form->input('article_title',array('type' => 'text', 'id'=>'ArticleHeader','div'=>false,'label'=>false,'class'=>'centertext',"placeholder"=>"Article Header"));
    echo $this->Html->para(null,'<br>', array());
    echo $this->Form->input('article_link',array('type' => 'text', 'id'=>'ArticleLink','div'=>false,'label'=>false,'class'=>'centertext',"placeholder"=>"Article Link"));
    echo $this->Html->para(null,'<br>', array());
    echo $this->Form->button('Cancel', array('type' => 'reset'), array('inline' => false));
    echo $this->Form->button('Save', array('type' => 'submit', 'disabled'=>true), array('inline' => false));

    echo $this->Form->end();
    ?>
</div>
<script>
$(':text').keyup(function() {
    if($('#ArticleHeader').val() != "" && $('#ArticleLink').val() != "") {
        $('#submit').removeAttr('disabled');
    } else {
        $('#submit').attr('disabled', true);
    }
});
</script>

解决了，抱歉浪费了所有人的时间提交有错误的标识符，需要冒号而不是哈希。即。

$(':text').keyup(function() {
    if($('#ArticleHeader').val() != "" && $('#ArticleLink').val() != "") {
        $(':submit').removeAttr('disabled');
    } else {
        $(':submit').attr('disabled', true);
    }
});
