Find ID in String using match - javascript

I'm building a widget that will generate a graph for an element when it is double clicked on the page. Without remaking all widgets this is the only way for me to tackle the problem.
I want find the ID of a widget from the html of an element.
All widgets I want to work are inside a div element panel_content_id_#
I want to find the number found on the line of code
var io_id=32715;
How can I search the string for this pattern and get the number (32715).
$('div[id^="panel_content_id_"]').dblclick(function(e){
console.log($(this).attr('id'));
var code = $(this).html();
// Find ID
var id = -1;
var search = code.match("var io_id=");
if(search > -1){
}
console.log($(this).html());
});
The line of code im looking for will look like so
var io_id=xxxxx;
Where xxxxx = some random number I dont know
I want to find xxxxx

Split it in two parts - All the code before the var io_id= and the other part is after that.
And then you know that the line ends with ;, so from that second part you cut of the stuff that is before the semicolon.
CODE
$('div[id^="panel_content_id_"]').dblclick(function(e){
console.log($(this).attr('id'));
var code = $(this).html();
// Find ID
var id = -1;
if (code.indexOf("var io_id")>-1) {
id = parseInt(code.split("var io_id=")[1].split(";")[0]);
}
if(search > -1){
console.log("The code betrayed me");
}
console.log("The id is: " +id);
});

Maybe you could try this regex pattern:
\d+(?! var io_id=)
Used like this:
$('div[id^="panel_content_id_"]').dblclick(function(e) {
console.log($(this).attr('id'));
var code = $(this).html();
// Find ID
var id = -1;
var search = code.match("var io_id=");
if (search) { // Edited
// New code
alert(code.match(/\d+(?! var io_id=)/gim));
}
console.log($(this).html());
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="panel_content_id_32715">
Div content
<br><br>
var io_id=32715;
</div>

Finding the missing sequence number in a file

Hi I have to find a missing number in an xml file. but I feel difficulty to find. Pls suggest some ideas.
Example
A file contains an <a> tag which include id i.e page-1,2... I need to find the missing numbers using jquery.
a.xml
<p>have a great <a id="page-1"/>day. How are you.</p>
<p><a id="page-2"/>Have a nice day.</p>
<p>How <a id="page-5"/>are you</p>
<p>Life is so exciting<a id="page-6"/></p>
My code
<script>
$(document).ready(function() {
$("#find").click(function(){
Fname = $("#myFile").val();
lpage = $("#lpage").val();
$.get(Fname, function(data){
var lines = data.split("\n");
if (lines.match(id="page-)) { //how to use regular exoreessi0n
alert("hi");
}
});
});
});
</script>
I'll take some assumptions regarding your input. Please add validations as necessary:
var lines = ['<p>have a great <a id="page-1"/>day. How are you.</p>',
'<p><a id="page-2"/>Have a nice day.</p>',
'<p>How <a id="page-5"/>are you</p>',
'<p>Life is so exciting<a id="page-6"/></p>'];
var sequences = [];
lines.forEach(function(line) {
// Not efficient but simple
// Let jQuery parse this string to object, so we won't need regexp
var obj = $(line);
// Assuming there's always A and ID attribute
var id = obj.find("a").attr("id").split("-");
// Assuming sequence is always last
sequences.push(parseInt(id[id.length - 1]));
});
sequences.sort();
// Again, inefficient, but will do the job
var last = sequences[sequences.length - 1];
for (var i = last; i >= 0; i--) {
if (sequences.indexOf(i) < 0) {
console.log(i + " is missing");
}
}

How to make a word count that contains html tags using javascript?

Hi I would like to do a Word Count in my RTE (Rich Text Editor) with javascript can also use with jquery. But it should not count the html tags and repeating white spaces.
Sample Text:
<p>11 22 33</p><p>44</p>5<br></div>
The javascript should display 5 only.
Is there any javascript code for this and that is also fast to calculate the Word Count?
Thanks!
Try something like this:
You get the html in the div then you remove all tags and replace them with spaces. You remove (trim) all left and right spaces and finally you split the string into an array. The length is your answer.
var cont = $("#content").html();
cont = cont.replace(/<[^>]*>/g," ");
cont = cont.replace(/\s+/g, ' ');
cont = cont.trim();
var n = cont.split(" ").length
alert(n);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div id="content">
<p>11 22 33</p><p>44</p>5<br></div>
var words = [];
function getWords(elements) {
elements.contents().each(function() {
if ($(this).contents().length > 0) return getWords($(this));
if ($(this).text()) words = words.concat($(this).text().split(" "));
})
}
getWords($('<div>').html('<p>11 22 33</p><p>44</p>5<br></div>'));
console.log(words,words.length);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
You can do something tricky by using jQuery by creating an element with the content.
var str = '<p>11 22 33</p><p>44</p>5<br></div>';
var len = 0;
// create a temporary jQuery object with the content
$('<div/>', {
html: str
})
// get al child nodes including text node
.contents()
// iterate over the elements
.each(function() {
// now get number or words using match and add
len += (this.textContent.match(/[\w\d]+/g) || '').length;
});
console.log(len);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
You can use Countable.js for live word counting, although it doesn't ignore HTML tags.

Get last part of the url

Trying to get the last part of the url in a pretty weird html structure. Don't ask why it's built that way. There is a very good reason behind it.
The html looks like this
<li class="lifilter"><input type="checkbox" class="filtercheck" id="Cheeks...">
<label for="Cheeks...">
Cheeks
</label>
</li>
and the js i'm trying to use
$('#Cheeks... label a').each(function(){
var lasturl = $(this).attr('href');
var urlsplit = url.split("/");
var finalvar = urlsplit[4];
$(this).addClass(finalvar);
});
edit: damn.. i can only post once every 90 minutes.
here is updated question with updated html
<li class="lifilter">
<input type="checkbox" class="filtercheck" id="Cheeks...">
<label for="Cheeks...">
Cheeks
</label>
</li>
and the js code i'm trying to use (from a previous answer)
$('.lifilter').each(function(){
$(this).find(".filtercheck").next('label').find('a').each(function(){
var lasturl = $(this).attr('href');
var urlsplit = lasturl.split("/");
console.log(urlsplit);
var finalvar = urlsplit.pop();
console.log('Adding class: ' + finalvar);
$(this).addClass(finalvar);
});
});
OK, so it appears no one here attempted to try the solution here before posting.
First things first cheeks.... This is a tricky ID to find (You have to escape the periods). The label is also not part of the internal html where ID is cheeks..., so we need to find the adjacent element and look the a anchor tag you're looking for.
Here's the code:
$(document).ready(function() {
$('#Cheeks\\.\\.\\.').next('label').find('a').each(function(){
var lasturl = $(this).attr('href');
var urlsplit = lasturl.split("/");
console.log(urlsplit);
var finalvar = urlsplit.pop();
console.log('Adding class: ' + finalvar);
$(this).addClass(finalvar);
});
});
And here is a working jsfiddle with the solution.
keeping it simple like your code you'd do
finalvar = urlsplit[urlsplit.length-1];
in case you don't want the base url as a valid return then:
finalvar = ( urlsplit.length > 1 ? urlsplit[urlsplit.length-1] : "" );
replace "" with your preferred error/default return
you could also try to find the index of the last '/' and do a substring.
try this.
FIDDLE DEMO
var URI = 'www.example.com/sub1/sub2/sub3/',
parts = URI.split('/'),
lastPart = parts.pop() == '' ? parts[parts.length - 1] : parts.pop();
//RESULT : "sub3"
You can extract the last section of a path (i.e. everything after the last /) by using a regular expression:
text.replace(/.*\//g, "")
This will remove all of the text before a slash, as well as the slash itself. You'll also notice that your selector wasn't matching any elements; you're looking for labels nested within inputs, which doesn't match the html you posted (and isn't a valid DOM structure). An appropriate selector would be .lifilter label a, since the <label> is within the <li>.
$(function() {
setTimeout(function() {
$('.lifilter label a').each(function() {
// strip everything up to and including the last forward slash
var path = $(this).attr('href').replace(/.*\//g, "");
$(this).addClass(path);
});
}, 1500);
});
a.cheeks:after {
content: " (className = 'cheeks')";
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<li class="lifilter">
<input type="checkbox" class="filtercheck" id="Cheeks...">
<label for="Cheeks...">
Cheeks
</label>
</li>
if you want the last section of url for example activation code or id.You can try this.
var url = 'www.abc.com/code=12345',
parts = url.split('='),
lastPart = parts.pop()
//lastPart = 12345

exclude the first string from being appended to a character

FIDDLE Example
I'm learning how to append all the data attributes from div.query elements to a url string: http://web.com?get=
With the script I can get this result:
"http://web.com?get=|Africa|Asia|Europe"
But is there any way not to have the first one coupled with "|" so that the url should be
"http://web.com?get=Africa|Asia|Europe"
I want to get that result because either http://web.com?get=|Africa|Asia|Europe
or http://web.com?get=Africa|Asia|Europe| would be invalid. Any suggestions?
JS:
$( document ).ready(function() {
$(".query").each(function() {
var div_terms = $(this).data('term'),
source = $('#main').data('source');
var x = source+'|'+div_terms;
$('#main').data('source',x);
$('.result').html(x);
});
});
HTML:
<div id="main" data-source="http://web.com?get="></div>
<div class="query" data-term="Africa"></div>
<div class="query" data-term="Asia"></div>
<div class="query" data-term="Europe"></div>
<div class="result"></div>
The easiest way is to pull all the countries to an array and join them using the pipe character.
var terms = $('.query').map( function() {
return $(this).data('term');
}).get().join('|');
var source = $('#main').data('source');
$('.result').html( source + terms );
Demo
http://jsfiddle.net/cHtT6/3/
You just need to replace the first '|' in the resulting url with an empty character ''.
Make it simple use javascript join function
$( document ).ready(function() {
var terms=[];
$(".query").each(function() {
var div_terms = $(this).data('term');
terms.push(div_terms);
});
var x = $('#main').data('source')+terms.join("|");
$('.result').html(x);
});
Fiddle here
Use an if statement to check if it's the first 'data-term'. If it is then don't use the | character. Then in the else statement you just do as you've already done
DEMO
Just Check whether end is reached like this:
$( document ).ready(function() {
var i=0;
$(".query").each(function() {
i++;
var div_terms = i==$(".query").length? $(this).data('term')+"":$(this).data('term')+"|",
source = $('#main').data('source');
var x = source+''+div_terms;
$('#main').data('source',x);
$('.result').html(x);
});
});
Here when last term is reached. Automatically only "" is appended in all other cases "|" is appended.

.clone doesn't not appear to be incrementing

this script is suppose to clone a new row of a HTML table. It does not seem to be incrementing the name, id, attributes. What am I doing wrong? The only other thing that is not working is get the value from the previous input id of #endtime_* and putting it in the cloned input id of #starttime_* although I think that is because it does seem to be incrementing as it clones a row.
<script type="text/javascript">
function MaskTime(){
var index = $("#TimeCard tbody>tr").length-1;
$('#endtime_'+index).mask("99:99 aa");
$('#starttime_'+index).mask("99:99 aa");
}
function update_rows(){
$("#TimeCard tbody>tr:odd").css("background-color", "#FFF");
$("#TimeCard tbody>tr:even").css("background-color", "#999");
}
$(document).ready(function() {
$("#addrow").click(function() {
var row = $('#TimeCard tbody>tr:last').clone(true).insertAfter('#TimeCard tbody>tr:last');
var index = $("#TimeCard tbody>tr").length-1;
var endvalue = $('#endtime_'+index-1).val();
$("td:eq(0) select").attr("name", 'type_'+index).attr("id", 'type_'+index).addClass("validate[required]").val('')
$("td:eq(1)").html(" ")
$("td:eq(2) select").attr("name", 'propid_'+index).attr("id", 'propid_'+index).addClass("validate[required]").val('')
$("td:eq(3)").html(" ")
$("td:eq(4) input").attr("name", 'starttime_'+index).attr("id", 'starttime_'+index).addClass("validate[required,custom[timeclock]]").val(endvalue)
$("td:eq(5) input").attr("name", 'endtime_'+index).attr("id", 'endtime_'+index).addClass("validate[required,custom[timeclock]]").val('')
$("td:eq(6)").html(" ")
update_rows();
MaskTime();
return false;
});
});
</script>
For the first part of your question:
It does not seem to be incrementing the name, id, attributes.
Your script isn't giving the proper context for where the tds are for which you want to modify the attribues, etc.
Here's a modification that corrects that, adding a new variable "newrow" (to reduce DOM calls) and modifying the lines of code related to td:eq(#)...
$(document).ready(function() {
$("#addrow").click(function() {
var row = $('#TimeCard tbody>tr:last').clone(true).insertAfter('#TimeCard tbody>tr:last');
var index = $("#TimeCard tbody>tr").length-1;
var endvalue = $('#endtime_'+index-1).val();
var newrow = $("#TimeCard tbody>tr:last");
newrow.children("td:eq(0)").children("select").attr("name", 'type_'+index).attr("id", 'type_'+index).addClass("validate[required]").val('')
newrow.children("td:eq(1)").html(" ")
newrow.children("td:eq(2)").children("select").attr("name", 'propid_'+index).attr("id", 'propid_'+index).addClass("validate[required]").val('')
newrow.children("td:eq(3)").html(" ")
newrow.children("td:eq(4)").children("input").attr("name", 'starttime_'+index).attr("id", 'starttime_'+index).addClass("validate[required,custom[timeclock]]").val(endvalue)
newrow.children("td:eq(5)").children("input").attr("name", 'endtime_'+index).attr("id", 'endtime_'+index).addClass("validate[required,custom[timeclock]]").val('')
newrow.children("td:eq(6)").html(" ")
update_rows();
MaskTime();
return false;
});
});
Also, I'd made a jsfiddle with the above: http://jsfiddle.net/m78UN/2/
I'm not following what you're wanting when you describe your second problem:
The only other thing that is not working is get the value from the previous input id of #endtime_* and putting it in the cloned input id of #starttime_*
...so I've not attempted to address that.
I think you can do everything you're doing in a way simpler way. I don't have your original HTML, but check this out as a possible alternative. It mainly does 3 things:
Removed IDs used for finding things
Caches selectors
Adds classes to time inputs to make them easier to reference
Removed MaskTime() function
Here's the code:
$(document).ready(function() {
var $timecard = $("#TimeCard");
var $tbody = $timecard.find("tbody");
var $rows = $tbody.children("tr");
$("#addrow").click(function(e) {
e.preventDefault(); // clearer than return false
var $lastRow = $tbody.find("tr:last-of-type");
var lastEnd = $lastRow.find(".endTime").val();
var $newRow = $lastRow.clone(true).appendTo($tbody);
var $cols = $newRow.find("td");
var index = $rows.length - 1;
$cols.eq(0).find("select").attr("name", 'type_' + index).addClass("validate[required]").val('');
$cols.eq(1).empty();
$cols.eq(2).find("select").attr("name", 'propid_' + index).addClass("validate[required]").val('');
$cols.eq(3).empty();
$cols.eq(4).find("input").attr("name", 'starttime_' + index).addClass("time startTime validate[required,custom[timeclock]]").val(lastEnd);
$cols.eq(5).find("input").attr("name", 'endtime_' + index).addClass("time endTime validate[required,custom[timeclock]]").val('');
$cols.eq(6).empty();
update_rows(); // no idea what this is
$newRow.find(".time").mask("99:99 aa"); // MaskTime() just did this
});
});
