I have a live search for a website and it's working just fine but I cannot seem to figure out how to highlight the search term in the result. Below is my JS code. I assume I need to edit the data-search-term variable but I am clueless about how to go about it.
I know only HTML/CSS. No JavaScript.
jQuery(document).ready(function($) {
$('.training-search-list li').each(function() {
$(this).attr('data-search-term', $(this).text().toLowerCase());
});
$('.training-search-box').on('keyup', function() {
var searchTerm = $(this).val().toLowerCase();
$('.training-search-list li').each(function() {
if ($(this).filter('[data-search-term *= ' + searchTerm + ']').length > 0 || searchTerm.length < 1) {
$(this).show();
} else {
$(this).hide();
}
});
});
});
Thanks in advance.
I made it long time ago
(function($){
$('#categoryFilter').focus().keyup(function(event){
var input = $(this);
var val = input.val();
if(val == ''){
$('#filter li').show();
$('#filter a span').removeClass('highlighted');
return true;
}
var regexp = '\\b(.*)';
for (var i in val) {
regexp += '('+val[i]+')(.*)';
}
regexp += '\\b';
$('#filter li').show();
$('#filter').find('a > span').each(function(){
var span = $(this);
var resultats = span.text().match(new RegExp(regexp,'i'));
if(resultats){
var string = '';
for (var i in resultats){
if(i > 0){
if(i%2 == 0){
string += '<span class="highlighted">'+resultats[i]+'</span>';
}else {
string += resultats[i];
}
}
}
span.empty().append(string);
}else {
span.parent().parent().hide();
}
});
});
})(jQuery);
Maybe you can try to make your own code with some part of mine

I am using this code
HTML:
<div id="message">some message</div>
<input type="text" id="myInput" />
jQuery:
$(function() {
$("#message").hide();
$("#fail").hide();
var prefix = ['HX', 'HD', 'BD', 'LS']
$('#myInput').keyup(function(e) {
var value = $(this).val();
var firstTwo = value.substr(0,2);
var firstTwoUpper = firstTwo.toUpperCase();
if(firstTwo != firstTwoUpper) {
$(this).val( value.replace(/^\w\w/, firstTwoUpper) );
}
if(value.length > 1) {
if($.inArray(firstTwoUpper, prefix) >= 0) {
$("#fail").hide();
$("#message:hidden").fadeIn();
} else {
$("#message").hide();
$("#fail:hidden").fadeIn();
}
} else {
$("#message").hide();
$("#fail").hide();
}
});
});
To be a post code check. I got the above code from here: Jquery check array perform function and it works just fine but I want to display a message containing a link which all differ from one another. For example I want code 'HX' to link to facebook and I want 'BD' to link to the BBC. How would I write the if statement correctly? I have tried various ways but I am not achieving what I need.
Could someone give me a little guideance please?
Thanks,
Ben.
This fiddle does what you might be looking for
<div id="message">Some link</div>
<div id="fail">Invalid postcode</div>
<input type="text" id="myInput" />
$(function () {
$("#message").hide();
$("#fail").hide();
var prefix = ['HX', 'HD', 'BD', 'LS'];
var links = ['http://www.facebook.com','http://www.example.com','http://www.bbc.com','#'];
$('#myInput').keyup(function (e) {
var value = $(this).val();
var firstTwo = value.substr(0, 2);
var firstTwoUpper = firstTwo.toUpperCase();
if (firstTwo != firstTwoUpper) {
$(this).val(value.replace(/^\w\w/, firstTwoUpper));
}
if (value.length > 1) {
var index = $.inArray(firstTwoUpper, prefix);
if (index >= 0) {
$("#fail").hide();
$("#message").fadeIn();
$("#message a").attr("href",links[index]).html(links[index])
} else {
$("#message").hide();
$("#fail:hidden").fadeIn();
}
} else {
$("#message").hide();
$("#fail").hide();

I changed prefix from an array of strings to an array of objects.
You're going to see an issue if users type really fast because of the speed of fadeIn().
$(function() {
$("#message").hide();
$("#fail").hide();
var prefix = [{code:'HX',link:'www.facebook.com'}, {code:'BD',link:'www.bbc.com'}];
$('#myInput').keyup(function(e) {
var value = $(this).val();
var firstTwo = value.substr(0,2);
var firstTwoUpper = firstTwo.toUpperCase();
if(firstTwo != firstTwoUpper) {
$(this).val( value.replace(/^\w\w/, firstTwoUpper) );
}
if(value.length > 1) {
for(var obj in prefix){
console.log(firstTwoUpper, prefix[obj].code, firstTwoUpper == prefix[obj].code);
if(firstTwoUpper === prefix[obj].code){
$("#fail").hide();
var link = ''+prefix[obj].link+'';
$("#message").append(link);
$("#message:hidden").fadeIn();
break;
}else {
$("#message").hide();
$("#fail:hidden").fadeIn();
}
};
} else {
$("#message").empty();
$("#message").hide();
$("#fail").hide();
}
});
});
$('#myInput').keyup(function (e) {
var value = $(this).val();
var firstTwo = value.substr(0, 2);
var firstTwoUpper = firstTwo.toUpperCase();
if (firstTwo != firstTwoUpper) {
$(this).val(value.replace(/^\w\w/, firstTwoUpper));
}
if (value.length > 1) {
if ($.inArray(firstTwoUpper, prefix) >= 0) {
if (firstTwoUpper == "HX") {
$("#message").empty();
$("#message").html('<p>some message</p>Google');
} else if (firstTwoUpper == "HD") {
$("#message").empty();
$("#message").html('<p>other message</p><a `enter code here`href="http://www.stackoverflow.com">Stack OverFlow</a>');
}
$("#fail").hide();
$("#message:hidden").fadeIn();
} else {
$("#message").hide();
$("#fail:hidden").fadeIn();
}
} else {
$("#message").hide();
$("#fail").hide();
}
});

I have 5 select fields with id's id1, id2,.. id5
and i need check if values (selected) not equal then highlight green and if equal then highlight red
but is look crazy validate each field 5 times? is posible use special functions ir validate easy than with:
if
if
if
if
I dont need a code just idea.
You can loop through each select to compare the values
$("select").change(function () {
flag = false;
var value = $(this).val();
$("select").each(function () {
if ($(this).val() != value)
flag = true;
});
if (flag)
$("select").css("color", "red");
else
$("select").css("color", "green");
});
Demo
Edit
$("select").change(function () {
var flag = true;
$("select").each(function () {
var outer = this;
$("select").not(outer).each(function () {
if ($(outer).val() == $(this).val()) {
flag = false;
return false;
}
});
});
if (flag)
$("select").css("color", "green");
else
$("select").css("color", "red");
});
Updated Fiddle
New update
I've simplified the code like this. YOu dont have to use nested loop if you do like this
$("select").change(function () {
var flag = true;
$("select").each(function () {
if ($("select").find("option:selected[value=" + this.value + "]").length > 1) {
flag = false;
return false;
}
});
if (flag)
$("select").css("color", "green");
else
$("select").css("color", "red");
});
Updated Fiddle
Try this one..
$("select").change(function(){
var selected = [];
var valiSel = [];
$('select > option:selected').each(function() {
if($(this).val() != 0){
selected.push( $(this).val() );
}
valiSel.push( $(this).val() );
});
var unique = unique12(selected);
var uniqueLength = unique.length;
var valiSelUnique = unique12(valiSel);
var selectedLength = selected.length;
if( unique.length != selected.length ){
alert( 'Two Selected value cannot be same' );
return false;
}
//return true;
});
function unique12(sel) {
var r = new Array();
o:for(var i = 0, n = sel.length; i < n; i++)
{
for(var x = 0, y = r.length; x < y; x++)
{
if(r[x]==sel[i])
{
//alert('this is a DUPE!');
continue o;
}
}
r[r.length] = sel[i];
}
return r;
}

on edit button click a want to submit form only if one check box checked,don't submit when 0 or more than 2 check box checked
my below code is not working
$("#editbtn_id").click(function () {
var cnt = 0;
var checkbox_value = "";
$(":checkbox").each(function () {
var ischecked = $(this).is(":checked");
});
if (ischecked) {
checkbox_value += $(this).val();
cnt = cnt + 1;
if (cnt == 0 || cnt > 1) {
alert(cnt);
alert("Please select one Test case");
return false;
}
}
return false;
});
HTML
<form action="/editSingletest/{{ testcase.id }}" method="post" onsubmit="return" >
<input type="checkbox"/>
</form>
You can achieve this by following code
$("#editbtn_id").click(function(){
var cnt=0;
var checkbox_checked_count = 0;
var form_submit = false;
$(":checkbox").each(function () {
if($(this).is(":checked")) {
checkbox_checked_count++
}
});
if(checkbox_checked_count == 1) {
form_submit = true;
}
else if(checkbox_checked_count > 1) {
alert("Please select one Test case");
}
alert(form_submit)
$("form").submit();
});
Check working example here in this fiddle
Your counter is in the wrong loop, should be something like this:
$("#editbtn_id").click(function(){
var cnt=0;
var checkbox_value = "";
$(":checkbox").each(function () {
var ischecked = $(this).is(":checked");
if (ischecked){
checkbox_value += $(this).val();
cnt=cnt + 1 ;
}
});
if(cnt==0 || cnt > 1){ ... }
});
try this
$("#editbtn_id").click(function (e) {
if($('form input[type="checkbox"]:checked').length == 1){
$('form').submit();
}
else{
e.preventDefault();
}
});
for 'form' use your form selector
I need to add an HTML anchor in my code. The fist code works fine but does not include the anchor tag that I need. But the second one fails:
This works fine, does not include :
<script type='text/javascript'>//<![CDATA[
$('#Quantity').keyup(function () {
var textualValue = $(this).val();
var numericValue = parseInt(textualValue, 10);
if (!isNaN(numericValue)) {
modifyDOMWithNumber(numericValue);
} else {
modifyDOMWithNumber(0);
}
});
function modifyDOMWithNumber(number) {
var ul = $('ul#ListToAlter').empty();
var item;
for (var i = 1; i <= number; i++) {
item = $("<li>");
if (i == 1) {
item.text("Options for your 1st $Name");
}else if(i == 2) {
item.text("Options for your 2nd $Name");
}else if(i == 3) {
item.text("Options for your 3rd $Name");
} else {
item.text("Options for your number " + i + "th $Name");
}
ul.append(item);
}
}
//]]>
</script>
This fails, does include :
<script type='text/javascript'>//<![CDATA[
$('#Quantity').keyup(function () {
var textualValue = $(this).val();
var numericValue = parseInt(textualValue, 10);
if (!isNaN(numericValue)) {
modifyDOMWithNumber(numericValue);
} else {
modifyDOMWithNumber(0);
}
});
function modifyDOMWithNumber(number) {
var ul = $('ul#ListToAlter').empty();
var item;
for (var i = 1; i <= number; i++) {
item = $("<li>");
if (i == 1) {
item.html("<a>Options for your 1st $Name</a>");
}else if(i == 2) {
item.html("<a>Options for your 2nd $Name</a>");
}else if(i == 3) {
item.html("<a>Options for your 3rd $Name</a>");
} else {
item.html("<a>Options for your number " + i + "th $Name</a>");
}
ul.append(item);
}
}
//]]>
</script>
Use
item.html("<a> what ever html text</a>")
instead of
item.text("<a> xxxx </a>").
Also note that in the code that fails, the for loop is missing, so i won't be defined.
The second piece of code, using item.html("<a>Options for your 1st $Name</a>"); probably works fine. But you are not inclusing an href attribute for the <a> element, which causes some browsers to not decorate the text as a link. In order for it to be decorated as a link (underline, characteristic color etc), you could replace it with:
item.html("Options for your 1st $Name");
See, also, this short demo.
$('#container form').delegate('#addSearch', 'keyup', function(e) {
var tmpVAL = $('#addSearch').val();
$('.w').each(function() {
var tmpHTML = $(this).html();
if (tmpHTML == tmpVAL) {
$(this).fadeIn(250);
} else if (tmpVAL.length < 1) {
$(this).fadeIn(250);
} else {
$(this).fadeOut(250);
}
});
});
and #addSearch is an <input type="text">.
So, my problem is that; this obviously will only return the results that are an exact match to the tmpVAL - How would I allow it so every letter will change the search result.
e.g.
I type N
it comes up with No, Not, Nothing, Nothingness
I type NOT
it comes up with Not, Nothing, Nothingness
Any help would be appreciated, I would imagine that it would be RegEx?
DEMO https://so.lucafilosofi.com/autocomplete-autofilter-using-jquery-delegate
$(function() {
$('#container form').delegate('#addSearch', 'keyup', function(e) {
var tmpVAL = $('#addSearch').val();
$('.w').each(function() {
var tmpHTML = $(this).text();
var subSection = tmpHTML.substring(tmpVAL.length, 0);
if (subSection == tmpVAL && tmpVAL != '' ) {
$(this).show();
} else {
$(this).hide();
}
});
});
});
You could use a regular expression, but I think that might be overkill. You could just use indexOf:
$('#container form').delegate('#addSearch', 'keyup', function(e) {
var tmpVAL = $('#addSearch').val().toLowerCase();
$('.w').each(function() {
var tmpHTML = $(this).html().toLowerCase();
if (tmpHTML.indexOf(tmpVAL) >= 0) {
$(this).fadeIn(250);
} else if (tmpVAL.length < 1) {
$(this).fadeIn(250);
} else {
$(this).fadeOut(250);
}
});
});
Working example: http://jsfiddle.net/andrewwhitaker/PRyvU/
Here's an alternative solution that doesn't use an .each():
$('#container form').delegate('#addSearch', 'keyup', function(e) {
var tmpVAL = $('#addSearch').val().toLowerCase();
var $words = $(".w");
var contains = function(haystack, needle) {
return haystack.indexOf(needle) >= 0;
};
if (tmpVAL.length < 1) {
$words.fadeIn(250);
}
else {
$words.filter(function() {
return !contains($(this).html().toLowerCase(), tmpVAL);
}).fadeOut(250);
$words.filter(function() {
return contains($(this).html().toLowerCase(), tmpVAL);
}).fadeIn(250);
}
});
