如何在更改选项值后点击“链接”按钮并单击“总结”? 我有问题,因为当我改变价值时,它会在我点击提交
之前进入“链接”<form action="search-form" method="post">
<select onChange="window.location.href=this.value" >
<option value="here comes a link nr 1">coffie medium</option>
<option value="here comes a link nr 2">coffe big</option>
</select>
<button type="submit" name="submit" value="submit"><img src="xyz.JPG" width="240" height="72">
</button>
</form>

从onchange
元素中删除select
并为您的提交按钮编写一个监听器(您已使用search-form
操作)
<form action="search-form" method="post">
<select>
<option value="here comes a link nr 1">coffie medium</option>
<option value="here comes a link nr 2">coffe big</option>
</select>
<button type="submit" name="submit" value="submit"><img src="xyz.JPG" width="240" height="72">
</button>
</form>

@Peril按要求添加解决方案。现在,如果您使用onsubmit
表格提交,则可以使用以下内容。请注意,您应该为option
值
function submit_form() {
window.location.href= document.getElementById('select-box').value;
}
<form onsubmit="submit_form()" method="post">
<select id="select-box">
<option value="http://google.com">coffie medium</option>
<option value="http://yahoo.com">coffe big</option>
</select>
<button type="submit" name="submit" value="submit">submit</button>
</form>
编辑2 :
@Peril通常,当我们点击anchor
标记时,我们会将外部链接加载到页面中。如果您使用window.location.href
加载,则会出现cross-origin access
错误。将以下代码段放入本地html文件并查看。
// load href initially
document.getElementById('form-button').setAttribute('action', document.getElementById('select-box').value);
// load href on value change of select
function onChangeValue() {
document.getElementById('form-button').setAttribute('action', document.getElementById('select-box').value);
return false;
}
<body>
<select id="select-box" onchange="onChangeValue()">
<option value="http://www.google.com">coffie medium</option>
<option value="http://www.facebook.com">coffe big</option>
</select>
<form action="#" id="form-button" style="display:inline">
<input type="submit" value="Submit" />
</form>
</body>

好的,如果您使用JavaScript或Jquery?
首先创建了选择:
<select name="form" id="form">
<option value="url">Home</option>
<option value="url">Contact</option>
<option value="url">Sitemap</option>
</select>
尝试.change以获取新位置:
$("#form").change(function(){
var url = $(this).val();
location.assign(url);
});
