我不太擅长编码，我的代码需要帮助。我有一个在数据库中搜索的代码。现在它显示数据库中的所有数据，当有人搜索时，它会过滤掉并在同一张表上显示结果。我只想显示结果，当有人在搜索栏上搜索时，它应该显示过滤后的数据.否则，我的表应该被隐藏。
谁能告诉我该怎么做。非常感谢您抽出宝贵时间。
<?php
if(isset($_POST['search']))
{
$valueToSearch = $_POST['valueToSearch'];
// search in all table columns
// using concat mysql function
$query = "SELECT * FROM `ADDRESS` WHERE CONCAT(`ID`, `STATE`) LIKE '%".$valueToSearch."%'";
$search_result = filterTable($query);
}
else {
$query = "SELECT * FROM `ADDRESS`";
$search_result = filterTable($query);
}
// function to connect and execute the query
function filterTable($query)
{
$connect = mysqli_connect("localhost:3306", "root", "dbadmin", "simplymac");
$filter_Result = mysqli_query($connect, $query);
return $filter_Result;
}
?>

最佳答案
您可以使用 ajax 来解决您的问题。 当客户在文本框中输入时调用一个java脚本函数，在该函数中获取文本框值并调用ajax获取结果表。
function getResult(search)
{
var file_path = '';//your php file path
$.ajax({
type: "POST",
url: file_path,
data: search,
cache: false,
success: function(result){
//print result in one div
}
});
} <input type="submit" name="search" value="SEARCH" class="Button" onClick="getResult(this.value);">关于javascript - 如何隐藏搜索栏上的结果表？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/44876317/
