我正在做一个项目,我似乎无法找到处理这个问题的最佳方法。我正在使用 jQuery Supersized 和选项框架来构建主题。除了图像之外,我拥有所有适用于滑块选项的东西。这是我的脚本

<script type="text/javascript">
    jQuery(function ($) {
        $.supersized({

            stop_loop: 0, // Pauses slideshow on last slide
            random: <? php echo of_get_option('random', '0'); ?> , // Randomize slide order (Ignores start slide)

            // Theme Options               
            progress_bar: 1, // Timer for each slide                            
            mouse_scrub: 0
        });
    });
</script>

我的所有设置都可以正常工作,但图像除外。有趣的是,当我查看源代码时,它会显示指向图像的链接,就像手动输入的链接一样。我试图将数据放入数组中,然后动态显示输出,但仍然不行。我在源代码中得到了相同的结果。{image :'http://buildinternet.s3.amazonaws.com/projects/supersized/3.2/thumbs/kazvan-1.jpg'},

为什么它不会从回声中加载图像,但它表明它在源中。

做这件事要非常非常非常小心。您直接输出到 Javascript 代码块,这意味着您的所有输出都必须创建语法上有效的 JS 代码。一个错误放置'可以杀死整个脚本块。

为了安全起见,您应该通过 json _encode() 进行所有输出,这可以保证您不会引入语法错误。

例如

random: <?php echo json_encode(of_get_option('random', '0')); ?> , // Randomize slide order (Ignores start slide)

考虑这样的情况:

<?php
$name = "Miles O'Brien";
?>

<script type="text/javascript">
var name = '<?php echo $name; ';
</script>

你最终会产生:

var name = 'Miles O'Brien';
                   ^--- syntax error, terminating the string early.

我建议用清晰的 php 代码创建 json,然后将该 json 包含到 javascript 表达式中。

代码会更好。

你犯错的机会更少(例如用引号)。

您需要确保在 php 大括号的任一侧放置引号,否则 javascript 不会将其作为字符串接收。例如

random                  :   '<?php echo of_get_option('random', '0'); ?>'
