我的朋友通过谷歌自定义搜索使用javascript向我发送一个示例，此结果将仅在提交搜索表单时显示来自网站的所有相关帖子/内容。
这是代码：
<html>
<head>
<script>
var hndlr = function($response) {
for (var i = 0; i < $response.items.length; i++) {
var item = $response.items[i];
// in production code, item.htmlTitle should have the HTML entities escaped.
document.getElementById("content").innerHTML += "<br>";
document.getElementById("content").innerHTML += "<br> Title : " + item.title;
document.getElementById("content").innerHTML += "<br> ==================================== ";
if (item.pagemap.hreview) {
for (var j = 0; j < item.pagemap.hreview.length; j++) {
document.getElementById("content").innerHTML += "<br>" + j + ": " + item.pagemap.hreview[j].description;
}
document.getElementById("content").innerHTML += "<br>";
}
}
}

然后我尝试使用gcse api插件在我的wordpress网站上执行此操作，但结果只显示标题和部分内容以及“阅读更多 - ＆gt;” ，
如何修改它以获取/显示所有内容？
这是插件的php文件：
