8,986 PointsJquery : Implement the search box at the top of the page that filters photos based on the captions.
Hey guys,
I have a quick question. I am pretty new to jquery and really haven't learned much from the courses so far. It seems that they are just jump all over the place. So I am working on a project where I am supposed to implement a search box and filter photos based on captions. I have no clue how to do this. I have searched google for two hours and haven't found much that really makes sense. I am wondering if anyone would know how to do this and if they would help me if possible. I appreciate any help that anyone can provide.
Thank you, Brandon

11,007 PointsDoes this work? I tested it in Jfiddle and it seemed to do what you want but I'm tired, it's late, and I don't have full paths to the images so I'm not completely sure. I hope this helps. If you do test this, let me know how it goes.
$('#search-bar').keyup(function()
{ var valThis = $(this).val().toLowerCase(); var noresult = 0; if(valThis === ""){
$('.galleryList > li').show();
noresult = 1;
$('.no-results-found').remove();
} else {
$('.galleryList > li').each(function(){
var text = $(this).text().toLowerCase();
var match = text.indexOf(valThis);
if (match >= 0) {
$(this).show();
noresult = 1;
$('.no-results-found').remove();
} else {
$(this).hide();
}
});
}
if (noresult === 0) { $(".galleryList").append('No results found.'); } });

8,986 PointsThis looks like it may work without issue. I am going to attempt a few things and I will let you know! Thank you!

8,986 PointsSure. Here is the jquery that I have so far. It kind of works...but I need to search based off of the alt attribute of the images. I can't figure out how to do that for the life of me. This code is just something I finally found and modified.
Javascript :
$('#search-bar').keyup(function(){
var valThis = $(this).val().toLowerCase();
var noresult = 0;
if(valThis == ""){
$('.galleryList > li').show();
noresult = 1;
$('.no-results-found').remove();
} else {
$('.galleryList > li').each(function(){
var text = $(this).text().toLowerCase();
var match = text.indexOf(valThis);
if (match >= 0) {
$(this).show();
noresult = 1;
$('.no-results-found').remove();
} else {
$(this).hide();
}
});
};
if (noresult == 0) {
$(".galleryList").append('<li class="no-results-found">No results found.</li>');
}
});
End of Javascript.
I will also post my unordered list below so you can see the contents of it.
HTML :
<ul id = "gallery-img" class = "galleryList">
<li>
<a href = "img/full-size/01.jpg" title = "Hay Bales" alt = "I love hay bales. Took this snap on a drive through the countryside past some straw fields."><img src = "img/thumb/01.jpg"></a>

</li>
</ul>
That should be all the code. Thank you.
