您好我想在数据库中运行搜索单词的功能。该功能位于此位置:媒体/搜索,到目前为止,可以通过“search_query”使用此JS运行此功能:
final_transcript = capitalize(final_transcript);
var queryTextField = document.getElementById("search_query");
queryTextField.value = final_transcript;
....
“search_query”在此输入中为id:
<form class="input-group navbar-form" action="<?php echo base_url();?>media/search" method="post"></li>
<li style="margin-top:8px;"><input type="text" class="form-control" placeholder="Search subtitles..." id="search_query" name="string" /></li>
<li style="margin:8px><button type="submit" class="btn btn-info" name="btn_search"><i class="search "></i></button>
我想更改它,所以我不想使用此HTML代码。我想在JS中实现“调用”功能媒体/搜索,而不是:
var queryTextField = document.getElementById("search_query");
答案 0 :(得分:0)
如果我误解了你,请告诉我,但如果我理解正确,你想用javascript触发搜索吗?
看起来你想在没有jQuery的情况下这样做吗?
//get search string inputted by user
var queryTextField = document.getElementById("search_query");
var query = queryTextField.value
//pass base url to javascript
var base_url = '<?php echo base_url();?>'
//create new request
var request = new XMLHttpRequest();
//set up what you want to do with returned data
request.onreadystatechange=function()
{
//if call was successful
if (request.readyState==4 && request.status==200)
{
//response will be in here
//request.responseText;
}
}
//set as post, the url, send asynchronously
request.open('POST', base_url+'media/search', true);
request.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded; charset=UTF-8');
request.send(query);
使用jQuery:
$.ajax({
type: 'POST',
url: base_url+'media/search',
data: query,
success: function(data_return) {
//do something with returned data
}
});

和

我没有测试过上面的代码,但它应该让你走上正确的道路。
