使用Google Images API
使用Google Images API
提问于 2011-08-19 01:43:38
我正在尝试使用Google的Images API来搜索图像，并将其作为div放入我的html文档中。这就是我到目前为止所拥有的，但似乎什么都没有出现。这是http://code.google.com/apis/imagesearch/v1/devguide.html的零件。这是我第一次使用API，所以我不确定到底是怎么回事。
<html>
<head>

<body>

<form name="upload" method="post" action="parse_image.php" enctype="multipart/form-data">
<input type="file" name="Image"><br>
<input type="submit" value="Upload Image">
</form>
<script type="text/javascript" src="https://www.google.com/jsapi?key=xxx"></script>
<script type="text/javascript" charset="utf-8">
google.load('search', '1');
function searchComplete(searcher) {
// Check that we got results
if (searcher.results && searcher.results.length > 0) {
// Grab our content div, clear it.
var contentDiv = document.getElementById('content');
contentDiv.innerHTML = '';
// Loop through our results, printing them to the page.
var results = searcher.results;
for (var i = 0; i < results.length; i++) {
// For each result write it's title and image to the screen
var result = results[i];
var imgContainer = document.createElement('div');
var title = document.createElement('h2');
// We use titleNoFormatting so that no HTML tags are left in the title
title.innerHTML = result.titleNoFormatting;
var newImg = document.createElement('img');
// There is also a result.url property which has the escaped version
newImg.src = result.tbUrl;
imgContainer.appendChild(title);
imgContainer.appendChild(newImg);
// Put our title + image in the content
contentDiv.appendChild(imgContainer);
}
}
}
function onload() {
// Our ImageSearch instance.
var imageSearch = new google.search.ImageSearch();
// Restrict to extra large images only
imageSearch.setRestriction(google.search.ImageSearch.RESTRICT_IMAGESIZE,
google.search.ImageSearch.IMAGESIZE_MEDIUM);
// Here we set a callback so that anytime a search is executed, it will call
// the searchComplete function and pass it our ImageSearch searcher.
// When a search completes, our ImageSearch object is automatically
// populated with the results.
imageSearch.setSearchCompleteCallback(this, searchComplete, [imageSearch]);
// Find me a beautiful car.
imageSearch.execute("Subaru STI");
}
google.setonloadCallback(onload);
</script>

它无法工作，因为您正在查找ID =‘HTMLElement’的内容，您没有任何具有该ID的元素

尝试将您的js函数放在<head></head>中
