这里我有排序选择框,我在更改选择框时执行了2个事件,首先设置隐藏值状态和第二个提交表单。
我需要提交具有更新隐藏值排序的表单,但是,每次我更改选择框表单都可以提前提交然后更新隐藏值。
因此,我需要延迟提交表格或在隐藏价值更新后提交表格。
你能指导我怎么做?
<amp-state id="sorting">
<script type="application/json">
{
"date_desc" : { "text" : "Most Recent", "type" : "desc", "by" : "date" },
"year_asc" : { "text" : "Year Ascending", "type" : "asc", "by" : "year" },
"year_desc" : { "text" : "Year Descending", "type" : "desc", "by" : "year" },
}
</script>
</amp-state>
<form target="_top" action="/amp/search" id="search" novalidate="" class="i-amphtml-form">
<input value="desc" type="hidden" name="search[order_type]" [value]="sorting[sort || ''].type" id="search_order_type">
<input value="top" type="hidden" name="search[order_by]" [value]="sorting[sort || ''].by" id="search_order_by">
</form
<select id="listing" name="listing" on="change:AMP.setState({sort:event.value}),search.submit">
<option value="date_desc">Most Recent</option>
<option value="year_asc">Year Ascending</option>
<option value="year_desc">Year Descending</option>
</select>

不是在客户端管理此状态,而是将<select>
值发送到服务器,然后使用服务器代码从<select>
值中提取类型和顺序可能更容易。
// This is an express sample, but you could apply
// the concept to any server technology.
app.post('/amp/search', (req, res) => {
/* ... */
let type, by;
if (req.body.listing === 'date_desc') {
by = 'date';
type = 'desc';
} else if (req.body.listing === 'year_asc') {
by = 'year';
type = 'asc';
} else if (req.body.listing === 'year_desc') {
by = 'year';
type = 'desc';
} else {
// error
}
/* render the sorted table response */
});
<form target="_top" action="/amp/search" id="search" novalidate="">
<select id="listing" name="listing" on="change:search.submit">
<option value="date_desc">Most Recent</option>
<option value="year_asc">Year Ascending</option>
<option value="year_desc">Year Descending</option>
</select>
</form>
这适合您的使用案例吗?或者你的表单中还有其他你不需要的东西吗?
