争夺
您基本上需要使用
利用它可以对单独的php脚本运行ajax请求。
基本上,您会有一个php脚本,代码设置如下:
让我们称它为句子.php
<?php
// Connect to database server
mysql_connect("localhost", "root", "password") or die (mysql_error ());
// Select database
mysql_select_db("login") or die(mysql_error());
// Get data from the database depending on the value of the id in the URL
$strSQL = "SELECT * FROM sentences WHERE id
ORDER BY RAND() LIMIT 1;";
//create an array with numbers 1-4
$order = array(1,2,3,4);
//shuffle them in random order
shuffle($order);
$rs = mysql_query($strSQL);
// Loop the recordset $rs
while($row = mysql_fetch_array($rs)) {
// Write the data of the person
//Display all the array values from 0-3 (array index starts from 0)
echo "<dt>Sentence:</dt><dd>" . $row[$order[0]] . " " . $row[$order[1]] . " " .
$row[$order[2]] . " " . $row[$order[3]] ."</dd>";
}
// Close the database connection
mysql_close();
?>
在script.js
中,您将运行jQuery
$(document).ready(function() {
$(document).on('click', '#showcontent', function(event) {
event.preventDefault();
$.get("sentence.php", function(data) {
$("div#content").html(data);
});
});
});
我已经试过了,但是数组没有出现在html页面上。只有“洗牌”按钮。@user3678617您是否修改了脚本以链接到实际文件?检查WebDeveloperTools控制台,看看是否有任何错误…没有发现错误,我已经修改了脚本以链接到html文件。但是senetence并没有出现接受洗牌按钮。@user3678617查看您的网络选项卡,是否看到ajax请求正在发送?
$(document).ready(function() {
$(document).on('click', '#showcontent', function(event) {
event.preventDefault();
$.get("sentence.php", function(data) {
$("div#content").html(data);
});
});
});
