Question

所以我不得不问一个问题，因为它还没有让我发表评论。我在这里使用RC提供的代码作为答案 Change image source with javascript

但是因为我的文件不是.html，它的.php和我的html代码都是echo，源代码最终看起来像这样：

这里是.php文件中包含的js

<script>
    function backColor(a) {
        document.getElementById("back_image").src=a;
    }
</script>

（谢谢RC！）

这里是.php

<?php
$cush_patterns = array();

$cush_patterns[101] = array(
    "pattern" => "Ocean Blue",
    "img" => "img/cush/blue.gif",
    "color" => "blue",
    "price" => 22.22
    );

$cush_patterns[102] = array(
    "pattern" => "Yellow sun",
    "img" => "img/cush/yellow.gif",
    "color" => "yellow",
    "price" => 28.99
    );

echo '<img id="back_image" src="img/cush/blue.gif">';
echo '<ul>';
echo'<li>';
echo '<img class="cush_showcase" src="' . $cush_pattern["img"] . '" onclick="backColor("' . $cush_pattern[img] . '");">';
echo '</li>';
echo '</ul>';
?>

这是我运行它时得到的源代码

<ul class="cush_show">
<li>
<img class="cush_showcase" src="img/cush/blue.gif" onclick="backColor("img/cush/blue.gif");">
<h6 id="patt_name">Ocean Blue</h6>
<h6 id="prices">$22.22</h6>
</li>
</ul>

<ul class="cush_show"><li>
<img class="cush_showcase" src="img/cush/yellow.gif" onclick="backColor("img/cush/yellow.gif");">
<h6 id="patt_name">Yellow sun</h6>
<h6 id="prices">$28.99</h6>
</li>
</ul>

这可能是显而易见的事情，但是我不能把手指放在它上面而且它让我疯了。

提前谢谢！

所以这是我在互联网上搜索后的解决方法。感谢@Tamil Selvan，@查尔斯约翰汤普森三世的评论，他们也帮助了！

<?php
$cush_patterns = array();

$cush_patterns[101] = array(
    "pattern" => "Deep ocean blue",
    "img" => "img/cush/blue.gif",
    "color" => "blue",
    "price" => 29.99
    );

$cush_patterns[102] = array(
    "pattern" => "Spring yellow",
    "img" => "img/cush/yellow.gif",
    "color" => "yellow",
    "price" => 28.99
    );

echo '<img id="back_image" src=\'' . $cush_patterns["img"] . '\'>';
echo '<ul class="cush_show">';
echo '<li>';
echo '<img class="cush_showcase" alt="Your patterns" src=\'' . $cush_pattern["img"] . '\' onclick="backColor(\'' . $cush_pattern["img"] . '\')">';
echo '</li>';
echo '</ul>';
?>

js在php文件上更改src
