停止提交表单的 Enter/Return 键
我正在尝试使用我在网上找到的 css 创建一个简单的搜索表单。我希望用户能够在文本框中点击 ENTER 键并让它运行查询,而无需用户单击按钮。我尝试检查 keydown 上的 ENTER 键,但由于某种原因页面不断刷新。这次刷新的原因是什么?

使用以下形式:
<div align="center" id="search">
<form class="searchform">
<input class="searchfield" style="color:#636363" type="text" value="Title/Album..." onkeydown="if (event.keyCode == 13) {querySong();}" onfocus="if (this.value == 'Title/Album...') {this.value = '';}" onblur="if (this.value == '') {this.value = 'Title/Album...';}" />
</form>
<form class="searchform">
<input class="searchfield" style="color:#636363" type="text" value="Artist..." onkeydown="if (event.keyCode == 13) {querySong();}" onfocus="if (this.value == 'Artist...') {this.value = '';}" onblur="if (this.value == '') {this.value = 'Artist...';}" />
<input class="searchbutton" type="button" value="Song" onclick="querySong()"/> 
<input class="searchbutton" type="button" value="Album" onclick="queryAlbum()"/>
</form>
</div>
