Hi all I am not sure how to approach this problem. I have a function
that is passed an array of HTML img elements. It loops through these
images checking the SRC attribute for images using a blank "no image"
thumb nail. It then executes an image search using the img tags ALT
attribute as the query. The callback function on the search then
replaces the Img SRC with the first image result.
I am having problems matching up the correct image with the
corresponding search callback. Right now I am just creating arrays and
matching the returned search with an index for the images. Since the
multiple searches run concurrently, depending on the size of the image
or network latency they can fire the call back out of order and mix up
the images.
I need an approach that lets me pair individual searches with html
elements. Would this be possible using a searchController and multiple
imageSearch objects?
Below is an example of the function I am using
google.load('search', '1');
function googleFillBlanks(jqueryImages){
//namePairs holds the images matching alt text and attachedCount is
used for matching up once the call back is fired
var attachedCount = 0;
var namePairs = [];
function searchComplete(searcher){
if (searcher.results && searcher.results.length > 0) {
var results = searcher.results;
var result = results[0];
$("img[alt='"+namePairs[attachedCount]+"'] ").attr('src',
result.tbUrl);
//jqueryImages.get(0).attr('src', result.tbUrl);
attachedCount++;
}
}
var imageSearch = new google.search.ImageSearch();
//restrict image size
imageSearch.setRestriction
(google.search.ImageSearch.RESTRICT_IMAGESIZE,
google.search.ImageSearch.IMAGESIZE_SMALL);
imageSearch.setSearchCompleteCallback(this, searchComplete,
[imageSearch]);
jqueryImages.each(function(){
if($(this).attr('src').substr(-12,8) == 'no_image')
{
namePairs.push($(this).attr('alt'));
imageSearch.execute($(this).attr('alt'));
}
});
}
