Question

我的页面中有以下结构：

page.php：

<html>
    <head>
        <title>Page title</title>
        <script src="jquery-2.0.3.js"></script>
        <script type="text/javascript">
            function search(value){
                window.location.href="page.php?search=" + value;
            }
        </script>
    </head>
    <body>
        <?php
            if(!empty($_GET['search'])){
                //SQL-statement with WHERE column LIKE $_GET['search']
            } else {
                //Other SQL-statement without WHERE column LIKE $_GET['search']
            }
        ?>
        <h1>Title</h1>
        <input type="text" onKeyUp="search(this.value);" 
               value="<?php echo $_GET['search']; ?>">
    </body>
</html>

正如您所读到的，重要的是，当按下spacebar时，它会在_和$_GET['search']字段中放置input，它是{ {1}}

Answer 1

也许尝试这样的替换：

var new_string = old_str.replace("&nbsp;", "_");

Answer 2

value是' '（单个空格）和 window.location.href="page.php?search=" + value; 将进行URL编码，因此空格将变为 （URL实体）

您必须urldecode($_GET['search']);将其变回空格字符。（http://us2.php.net/urldecode）

Answer 3

试试这个，

<?php
    if(isset($_GET['search']) && !empty($_GET['search'])){
         $q=urldecode($_GET['search']);// use it in your query
         //SQL-statement with WHERE column LIKE $_GET['search']
    } else {
        //Other SQL-statement without WHERE column LIKE $_GET['search']
    }
?>

阅读urldecode()

php：检查键盘上的按下按钮
