jQuery / js toLowercase - javascript

I can't turn searchBox to a .toLowerCase and my code is case sensitive because of this. I want the code to scan on both upperCase and lowerCase letters.
I wasn't able to find a solution to my problem.
<script>
$("#searchBtn").keyup(function () {
var searchBox = $("#searchBtn").val();
var returnRows = [];
$('tr').not('.headerRow').each(function () {
var addRow = true;
var $currentRow = $(this);
$currentRow.find('td').each(function () {
var $td = $(this);
var word = $td.text();
if (word.indexOf(searchBox) > -1) {
addRow = false;
return false;
// console.log("KOMT IN IF STATEMENT"); //sla deze rij op in een tijdelijke array
}
});
if (addRow) {
returnRows.push($currentRow)
}
});
if (true)
{
$('tr').show();
}
$.each(returnRows, function (i, v) {
$(v).hide();
});
});
</script>

I am not sure but you are making it a bit more complicated. Try something like this:
$("#searchBtn").keyup(function() {
var word = $("#searchBtn").val(),
timer;
if(timer){ clearTimeout(timer); }
timer = setTimeout(function(){
$('tr').not('.headerRow').filter(function(){
var txt = $(this).find('td').text();
return txt.indexOf(word) !== -1 && txt === word;
}).hide();
},900);
});
=== lets you compare strictly. So, in such case T !== t would result in true.

How to display default message when no results found on Jquery search filter

I'm currently building a page where a search field acts as a filter. It works perfectly fine and shows data against related word, but there is one issue that I'd like to solve. When the entered string or other words is not found in all the existing the page remains blank.
How could I display a default message on my page when no results are found by the filter? Something like a simple <p> explaining that no results were found.
The idea is to display it only once as long as the string is not found.
$('#search_field').on('keyup', function() {
var value = $(this).val();
var patt = new RegExp(value, "i");
$('#userFind').find('tr').each(function() {
var $table = $(this);
if (!($table.find('td').text().search(patt) >= 0)) {
$table.not('.t_head').hide();
}
if (($table.find('td').text().search(patt) >= 0)) {
$(this).show();
}
});
});
This is untested since you haven't provided any table to your question.
After you have looped though all tr, then check if any is visible. If not then append a tr with custom message and remove it and new search.
$('#search_field').on('keyup', function() {
var value = $(this).val();
// console.log(value);
var patt = new RegExp(value, "i");
$(".noRecord").remove();
$('#userFind').find('tr').each(function() {
var $table = $(this);
if (!($table.find('td').text().search(patt) >= 0)) {
$table.not('.t_head').hide();
} else {
$(this).show();
}
});
if ($('#userFind tr:visible').length == 0) {
$('#userFind tbody').append("<tr class='noRecord'><td>No records found.</td></tr>")
}
});
Assuming you have a div:
<div id="zeroHits">no results were found</div>
You can hide/show the #zeroHits div as follows:
$('#search_field').on('keyup', function() {
var value = $(this).val();
var patt = new RegExp(value, "i");
var zeroHits = true;
$('#userFind').find('tr').each(function() {
var $table = $(this);
if (!($table.find('td').text().search(patt) >= 0)) {
$table.not('.t_head').hide();
}
if (($table.find('td').text().search(patt) >= 0)) {
$(this).show();
zeroHits = false;
}
});
if(zeroHits) {
$('#zeroHits').show();
} else {
$('#zeroHits').hide();
}
});
Try this untested code
post your HTML and I can test
const $rows = $('#userFind tbody tr'); // only tbody rows
$('#search_field').on('keyup', function() {
var value = $(this).val();
// console.log(value);
var patt = new RegExp(value, "i");
$rows.each(function() {
const found = $(this).find('td').filter(function() {
return $(this).text().search(patt) != -1
}).length > 0
$(this).toggle(found);
});
$("#notFound").toggle($rows.filter(":visible").length === 0)
});

How to put a condition in jQuery's map function?

I am trying to put a condition in jQuery's map function. My issue is that I don't want the same number in the map function value. When it is the same I want to display an alert box. My map function code is like this:
var rankbox= $('input[type=text][class = cate_rank]').map(function() {
return this.value;
}).get();
If I get a value like 1,2,3,4,5 it's ok, but if I get a value like 1,2,3,2,5, I want to display an alert box. Is it possible?
How to put a condition in jQuery's map function?
function change_rank() {
var rankbox= $('input[type=text][class = cate_rank]').map(function() {
if() {
} else { }
return this.value;
}).get();
var vals = []
$('input[type=text][class = cate_rank]').each(function(){
if($(this).val() && (typeof vals[$(this).val()] == 'undefined')){
vals[$(this).val()] = 1;
var last_val = $(this).val();
}else if($(this).val() && (typeof last_val != 'undefined') && parseInt(last_val) > parseInt($(this).val())){
alert('Whooah! Something went terribly wrong! Inputs don\'t have values ordered incrementally!');
}else{
alert('Whooah! Something went wrong! We got two inputes with same value!');
}
});
Check this,
var rankbox= $(".test").map(function() {
return this.value;
}).get();
var sorted_arr = rankbox.slice().sort();
var results = [];
for (var i = 0; i < rankbox.length - 1; i++) {
if (sorted_arr[i + 1] == sorted_arr[i]) {
results.push(sorted_arr[i]);
}
}
var rankbox= $(".test").map(function() {
if($.inArray(this.value, results) > -1){
alert(this.value+" is duplicate");
}
return this.value;
}).get();
I took reference of this link
If you are Looking to check dup you can try this:
var x=[1,2,3,2,5]
var has=!x.every(function(v,i) {
return x.indexOf(v) == i;
});
console.log(has);//true means dup found else not found.
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
you can try with a object. check this:
function change_rank() {
var temp = {};
var rankbox= $('input[type=text][class = cate_rank]').map(function() {
if(temp[this.value]==undefined) {
temp[this.value] = this.value;
} else {
alert('the same value');
}
return this.value;
}).get();

Any better way to declare variables avoiding repetition of code?

Here is the js code which i am trying to use. I don't like the same code repeating again and I couldn't help myself to do this in a better way.
$(function(){
$('[data-behavior~=quick-reject]').on("click", function(){
var form = $(this).closest("[data-behavior~=modal-footer]").find("form");
var some_action = form.find("#some_actions").val();
var some_reasons = form.find("[data-behavior~=escalation-reason-select-box]");
if((some_reasons.val() === "") && ( some_action === "reject")){
var errorReason = "Please select a reason";
form.addClass("error").
parent().
find("div.error").
html(errorReason);
}else{
form.submit();
}
});
$(document).on("change", "#some_actions", function (){
var form = $(this).closest("[data-behavior~=modal-footer]").find("form");
var some_action = form.find("#some_actions").val();
var some_reasons = form.find("[data-behavior~=escalation-reason-select-box]");
if(some_action === "verify"){
some_reasons.hide();
}else{
some_reasons.show();
}
});
});
You could just make a little utility function, something like.
function getVars(that) {
var form = $(that).closest("[data-behavior~=modal-footer]").find("form");
return {
form: form,
some_action: form.find("#some_actions").val(),
some_reasons: form.find("[data-behavior~=escalation-reason-select-box]")
}
}
$('[data-behavior~=quick-reject]').on("click", function(){
var v = getVars(this);
if((v.some_reasons.val() === "") && ( v.some_action === "reject")){
var errorReason = "Please select a reason";
v.form.addClass("error").
parent().
find("div.error").
html(errorReason);
}else{
v.form.submit();
}
});
$(document).on("change", "#some_actions", function (){
var v = getVars(this);
if(v.some_action === "verify"){
v.some_reasons.hide();
}else{
v.some_reasons.show();
}
});

Programmatically change class names

I'm trying to increase/decrease a number contained in a class name of an element.
Let's consider this code :
Increase
Decrease
<div id="my_div" class="large-12 columns">Div content</div>
I would like to achieve something like this :
$('a.decrease').click(function(e){
e.preventDefault();
$('#my_div').decreaseClass('class^=large-');
//decrease the number at the end of the class(es)
//starting with the name "large-"
//in this case large-12 would go to large-11
});
Any idea how to go about it?
Updated Answer
I refined the jQuery plugin to improve its functionality. There we have an .alterClass() method to increase/decrease the number of class (by step config):
;(function ($) {
$.fn.alterClass = function (cls, opt) {
opt = opt || {};
var conf = $.extend({}, {
'min': 1, // min number of the class
'max': 12, // max number of the class
'step': 1 // increment/decrement step
}, opt);
return this.each(function () {
var oldClass = $.grep(this.className.split(" "), function (v, i) {
return v.indexOf(cls) === 0;
}).join(),
oldNum = Number(oldClass.split('-')[1]),
newClass;
oldNum += conf.step;
if (conf.step > 0) { // increase mode
newClass = cls + (oldNum <= conf.max ? oldNum : conf.max);
} else { // decrease mode
newClass = cls + (oldNum >= conf.min ? oldNum : conf.min);
}
if (! $(this).hasClass(newClass)) {
$(this).removeClass(oldClass).addClass(newClass);
}
});
};
}(jQuery));
You could set the min and/or max numbers and the step as well:
$('.increase').click(function(e) {
e.preventDefault();
$('#my_div').alterClass('large-', {'step': 1});
});
$('.decrease').click(function(e) {
e.preventDefault();
$('#my_div').alterClass('large-', {'step': -1});
});
Here is the UPDATED DEMO.
Original Answer
Here's my attempt to create the .decreaseClass() method:
;(function($) {
$.fn.decreaseClass = function(cls) {
return this.each(function() {
var oldClass = $.grep(this.className.split(" "), function(v, i){
return v.indexOf(cls) === 0;
}).join(),
oldNum = oldClass.split('-')[1];
$(this).removeClass(oldClass).addClass(cls+--oldNum);
});
};
}(jQuery));
You could use the above plugin as follows:
$('.decrease').click(function(e) {
e.preventDefault();
$('#my_div').decreaseClass('large-');
});
WORKING DEMO.
Simply loop through your classes and remove the class they are at and add the class they are going to. For example:
for (var i = 12; i > 1; i--) {
$('#my_div .large-'+i).removeClass('large-'+i).addClass('large-'+(i-1));
}
Where #my_div is the div you are doing this in and large- is the prefix. I made the assumption that if you are at large-1 you'll just stay there.
you are looking for removeClass and addClass
removeClass support function, remove pattern class is very easy. so you can do in this way:
$('#my_div').removeClass(function(index, css) {
return (css.match(/\blarge-\S+/g) || []).join(' ');
})
in your case.
var matchClass;
$('#my_div').removeClass(function (index, css) {
matchClass = css.match(/\blarge-\S+/g);
return (matchClass || []).join(' ');
});
matchClass=matchClass.map(function (item) {
item = item.split("-");
--item[item.length - 1];
console.log(item);
return item.join("-");
});
$('#my_div').addClass(matchClass.join(" "));
I made a example jsfiddle
-------------Update----------
if you like plugin, you can go this way:
(function () {
$.fn.riseClass = function (prefix,direct) {
var matchClass;
return this.each(function () {
$(this).removeClass(function (index, css) {
var regex=RegExp('\\b'+prefix+'-\\S+', "g");
matchClass = css.match(regex);
return (matchClass || []).join(' ');
});
matchClass = matchClass.map(function (item) {
item = item.split("-");
if (direct == "down") {
item[item.length - 1]--;
} else {
item[item.length - 1]++;
}
return item.join("-");
});
$(this).addClass(matchClass.join(" "));
});
};
})();

I try to figure out where and how I can make a split/add space between numbers and letters. Cause some people type for example "ip1500" and the script cant match the input with an element that is like "ip 1500". My problem ist that Im a js beginner.
I was trying and trying but i cant get it work. I also tried this
I found this spot and I think it can be done here where the everything get splitted by an " " (space):
prepareQuery: function (val) {
return val.toLowerCase().split(' ');
},
Would be very nice if somebody can help me.
If you want "123abc345def" to "123 abc 345 def". The replace function may help. The code is like this.
var str = "123abc345def";
str = str.replace(/(\d+)/g, function (_, num){
console.log(num);
return ' ' + num + ' ';
});
str = str.trim();
The code you linked didn't work mainly because it's using a different programming language to javascript. In theory, it should work, but javascript does not support regular expression lookbehinds (at this present time)..
Instead, I have re-wrote that fragment of code:
prepareQuery: function (val) {
function isNotLetter(a){
return (/[0-9-_ ]/.test(a));
}
var val=val.toLowerCase().split("");
var tempArray=val.join("").split("");
var currentIndex=1;
for (var i=0;i<val.length-1;i++){
if (isNotLetter(val[i]) !== isNotLetter(val[i+1])){
tempArray.splice(i+currentIndex, 0, " ");
currentIndex++;
}
}
return tempArray.join("");
}
Since you're new to javascript, I'm going to explain what it does.
It declares a function in prepareQuery to check whether or not a string contains a letter [this can be moved somewhere else]
It then splits val into an array and copies the content of val into tempArray
An index is declared (explained later)
A loop is made, which goes through every single character in val
The if statement detects whether or not the current character (val[i] as set by the loop) is the same as the character next to it (val[i+1]).
IF either one are different to the other (ie the current character is a letter while the next isn't) then a space is added to the tempArray at that "index"
The index is incremented and used as an offset in #6
The loop finishes, joins the "array" into a string and outputs the result.

(JSFiddle was down....)
EDIT:
Sorry, but I completely misinterpreted your question... You failed to mention that you were using "quicksearch" and jQuery. In that case I'm assuming that you have a list of elements that have names and you want to search through them with the plugin...
A much easier way to match the user's query (if there is no space) is to strip the space from the search table along with the query itself - though original reverse method will work (just not as efficiently) [aka: expanding the user's query]
In this case, stripping the space from both the search table and user input would be a better method
prepareQuery: function (val) {
return val.toLowerCase().replace(/ /ig,'').split(" ");
},
testQuery: function (query, txt, _row) {
txt=txt.toLowerCase().replace(/ /ig,'');
for (var i = 0; i < query.length; i += 1) {
if (txt.indexOf(query[i]) === -1) {
return false;
}
}
return true;
}

Edit 2:
It seems like your real intent is to create a fully functioning search feature on your website, not to just add spaces between letters and numbers. With this, I suggest using Quicksilver. I would love to work out an algorithm to extend quickSearcher but at the current time I cannot (timezones). Instead, I suggest using Quicksilver
