我有一个使用PHP jQuery和ajax的简单的ajax实时搜索脚本。这一切都很好，但输入框没有完全清除，所以结果框不会消失，除非我手动清除它..
JS -
@echo off

PHP -
<script type="text/javascript">
$(document).ready(function(){
$('.search-box input[type="text"]').on("keyup input", function(){
/* Get input value on change */
var inputVal = $(this).val();
var resultDropdown = $(this).siblings(".result");
if(inputVal.length){
$.get("backend-search.php", {term: inputVal}).done(function(data){
// Display the returned data in browser
resultDropdown.html(data);
});
} else{
resultDropdown.empty();
}
});
// Set search input value on click of result item
$(document).on("click", ".result", function(){
$(this).parents(".search-box").find('input[type="text"]').val($(this).text());
$(this).parent(".result").empty();
});
});
</script>
HTML -
$user = $_GET['user'];
$term = mysqli_real_escape_string($conn, $_REQUEST['term']);
if(isset($term)){
// Attempt select query execution
$sql = "SELECT * FROM prospects WHERE dealer_name LIKE '" . $term . "%'";
if($result = mysqli_query($conn, $sql)){
if(mysqli_num_rows($result) > 0){
while($row = mysqli_fetch_array($result)){
$dealer_name = $row['dealer_name'];
echo "<form method='post' class='editForm'>
<input type='hidden' name='dealer' value='$dealer_name'/>
<input type='submit' id='subDealer' value='$dealer_name'/>
</form>";
}
// Close result set
} else{
echo "<p>No matches found</p>";
}
} else{
echo "ERROR: Could not able to execute $sql. " . mysqli_error($conn);
}
}
就像它说它一切正常但输入字段（#searchBox）中有空白空格，不允许.result清除..
谢谢！

尝试以下代码段
// Set search input value on click of result item
$(document).on("click", ".result", function(){
$(this).parents(".search-box").find('input[type="text"]').val($(this).text().trim());
});
$(document).on('click', 'input[type=submit]', function() {
// This is NOT the best practice. But it works. Try to change your implementation to a better one!
setTimeout(function() {
$('.result').empty();
}, 1000);
return true;
}

使用jQuery trim（）函数
<script type="text/javascript">
$(document).ready(function(){
$('.search-box input[type="text"]').on("keyup input", function(){
/* Get input value on change */
var inputVal1 = $(this).val();
var inputVal = $.trim(inputVal1);
var resultDropdown = $(this).siblings(".result");
if(inputVal.length){
$.get("backend-search.php", {term: inputVal}).done(function(data){
// Display the returned data in browser
resultDropdown.html(data);
});
} else{
resultDropdown.empty();
}
});
// Set search input value on click of result item
$(document).on("click", ".result", function(){
$(this).parents(".search-box").find('input[type="text"]').val($(this).text());
$(this).parent(".result").empty();
});
});
</script>
