I have a url like "http://localhost:8080/myapp?age=12&add=mumbai&name=myname"
Now I want to add one parameter(tel=12345) as the first parameter in the query string like
"http://localhost:8080/myapp?tel=12345&age=12&add=mumbai&name=myname"
I have tried below snippet
var str = "http://localhost:8080/myapp?age=12&add=mumbai&name=myname";
var txt2 = str.slice(0, str.indexOf("?")) + "tel=12345&" + str.slice(str.indexOf("?"));
alert(txt2);
But the result is incorrect
http://localhost:8080/myapptel=12345&?age=12&add=mumbai&name=myname
Is there a better way???
Try this:
var str = "http://localhost:8080/myapp?age=12&add=mumbai&name=myname";
var txt2 = str.slice(0, str.indexOf("?")) + "?" + "tel=12345&"
// ^^^^^
+ str.slice(str.indexOf("?") + 1);
// ^^^
alert(txt2);
You need to just increment index by 1 and this will work.
E.g.:
var txt2 = str.slice(0, str.indexOf("?") + 1 ) + "tel=12345&" + str.slice(str.indexOf("?") + 1);
var txt2=str.split('?')[0]+'?tel=12345&'+str.split('?')[1];
Just a variation.

The code is used in a HTML document, where when you press a button the first word in every sentence gets marked in bold
This is my code:
var i = 0;
while(i < restOftext.length) {
if (text[i] === ".") {
var space = text.indexOf(" ", i + 2);
var tekststykke = text.slice(i + 2, space);
var text = text.slice(0, i) + "<b>" + tekststykke + "</b>" + text.slice(i + (tekststykke.length + 2));
var period = text.replace(/<b>/g, ". <b>");
var text2 = "<b>" + firstWord + "</b>" + period.slice(space1);
i++
}
}
document.getElementById("firstWordBold").innerHTML = text2;
}
It's in the first part of the code under function firstWordBold(); where it says there is an error with
var space1 = text.indexOf(" ");
Looks like you're missing a closing quote on your string, at least in the example you provided in the question.
Your problem is the scope of the text variable. In firstWordBold change every text to this.text, except the last two where you re-define text
Also, if you want to apply bold to the first word this is easier...
document.getElementById('test-div-2').innerHTML = '<b>' + firstWord + '</b>' + restOftext;
It now works for me, with no errors and it applies bold to the first word.
Here's how the function ended up,
function firstWordBold() {
console.log('bolding!');
var space1 = this.text.indexOf(' ');
var firstWord = this.text.slice(0, space1);
var restOftext = this.text.slice(space1);
document.getElementById('test-div-2').innerHTML = '<b>' + firstWord + '</b>' + restOftext;
}
To make every first word bold, try this...
function firstWordBold() {
let newHTML = '';
const sentences = this.text.split('.');
for (let sentence of sentences) {
sentence = sentence.trim();
var space1 = sentence.indexOf(' ');
var firstWord = sentence.slice(0, space1);
var restOftext = sentence.slice(space1);
newHTML += '<b>' + firstWord + '</b>' + restOftext + ' ';
}
document.getElementById('test-div-2').innerHTML = newHTML;
}
One last edit, I didn't notice you had sentences ending with anything other that a period before. To split on multiple delimiters use a regex, like so,
const sentences = this.text.split(/(?<=[.?!])\s/);
I am having a string like this:
"welcome country !
and some texts
Keyword1:the value
keyword2: the value2"
I want to remove keyword on undo the corresponding checkbox and also its value using Javascript. Now i could remove the keyword while undo checkbox but not the value they have entered near the keyword.
I have tried substring functions and some other, but i couldn't fix it.
my code below:
$("#txtNote").val(url.replace($(this).attr("data-id") + ":", ""));
I just want to remove the texts immediately after the ":"
here is my entire code:
if ($(this).attr("data-selected1") == "true") {
$("#detailChronic").show();
$(this).attr("data-selected1", "false");
//$(".hjk").remove(":contains('" + $(this).attr("data-id") + "')");
var url = $.trim($("#txtNote").val());
str = $("#txtNote").val();
//var t = str.substring(str.indexOf(":"))
//alert(t);
//url = url.replace(/\s+/g, "\n");
// $("#txtNote").val(url.replace($(this).attr("data-id") + ":", ""));
// $("#txtNote").val(url.replace($(this).attr("data-id") + ":" + $(this).attr("data-id").value(), ""));
//url.replace($(this).attr("data-id") + ":", "");
alert(url);
var temp2 = temp1.replace(/($(this).attr("data-id"))(\:(.*))/, "");
alert(temp2);
var temp1 = url.replace($(this).attr("data-id"), "");
alert(temp1);
$("#txtNote").val(temp1);
// $("#txtNote").val(url.replace($(this).attr("data-id") + ":" + $(this).attr("data-id").value(), ""));
if ($("#selectedList").html() == "") {
$("#detailChronic").hide();
}
}
if you want to remove 'Keyword1:the value', then try
var keyWordToRemove = 'Keyword1';
var rgxStr = keyWordToRemove + ':[a-zA-Z0-9 ]*\n';
var rgx = new RegExp(rgxStr,'g');
var text = `welcome country !
and some texts
Keyword1:the value
keyword2: the value2`;
console.log(text);
text = text.replace(rgx,"");
console.log(text);
Hope it helps :)
You can try it using regex like this
var url = `welcome country !
and some texts
Keyword1:the value
keyword2: the value2`;
console.log(url.replace("Keyword1:", "test key "))
console.log(url.replace(/(Keyword1)(\:(.*))/, "$1 test value"))
you can replace Keyword1 with $(this).attr("data-id") + ":" in your code
I have a set of urls that i need to get a specific part of . The format of the url is :
http:\/\/xxx.xxxxx.com\/xxxx\/xxxx\/1234567_1.jpg
I need to get the 1234567 bit and store that in a var.
Well you can do splits
"http://xxx.xxxxx.com/xxxx/xxxx/1234567_1.jpg".split("/").pop().split("_").shift()
or a regular expression
"http://xxx.xxxxx.com/xxxx/xxxx/1234567_1.jpg".match(/\/(\d+)_\d+\.jpg$/).pop()
You should be able to get it to work with your JSON string by checking the URL with a function. Something like this should work:
function checkForMatches(str) {
var res = str.match(/.*\/(.*)_1.jpg/);
if(res) {
output = res[res.length-1];
} else {
output = false;
}
return output;
}
$.get("test.php", function (data) {
// now you can work with `data`
var JSON = jQuery.parseJSON(data); // it will be an object
$.each(JSON.deals.items, function (index, value) {
//console.log( value.title + ' ' + value.description );
tr = $('<tr/>');
tr.append("<td>" + "<img class='dealimg' src='" + value.deal_image + "' >" + "</td>");
tr.append("<td>" + "<h3>" + value.title + "</h3>" + "<p>" + value.description + "</p>" + "</td>");
//tr.append("<td>" + value.description + "</td>");
tr.append("<td> £" + value.price + "</td>");
tr.append("<td class='temperature'>" + value.temperature + "</td>");
tr.append("<td>" + "<a href='" + value.deal_link + "' target='_blank'>" + "View Deal</a>" + "</td>");
myvar = checkForMatches(value.deal_link);
if(myvar == false) {
myvar = value.deal_link; //if no matches, use the full link
}
tr.append("<td>" + "<a href='" + myvar + "' target='_blank'>" + "Go To Argos</a>" + "</td>");
$('table').append(tr);
});
});
Earlier, more basic examples.
You can use a regular expression to find the match.
Something like this would work:
var str = "http:\/\/xxx.xxxxx.com\/xxxx\/xxxx\/1234567_1.jpg";
var res = str.match(/.*\/(.*)_1.jpg/);
alert(res[1])
If you wanted to go a little further with it, you could create a function and pass the strings you wanted to test, and it would return the matched value if found, or boolean false if no matches exist.
Something like this would work:
function checkForMatches(str) {
var res = str.match(/.*\/(.*)_1.jpg/);
if(res) {
output = res[res.length-1];
} else {
output = false;
}
return output;
}
alert(checkForMatches("http:\/\/xxx.xxxxx.com\/xxxx\/xxxx\/1234567_1.jpg"))
alert(checkForMatches("this is an invalid string"))
You can see it working here: https://jsfiddle.net/9k5m7cg0/2/
Hope that helps!
var pathArray = window.location.pathname.split( '/' );
to split 1 / 2/ 3/ 4...
So to get path 2 it would be:
var setLocation = pathArray[1];
Well This should do
function getLastFolder(){
var path = window.location.href;
var folders =path.split("/");
return folders[folders.length-1]);
}
Here's the idea: take everything that comes after the final / character, and then take everything within that substring that comes before the first _ character.
var getUrlTerm = function(url) {
var urlPcs = url.split('/');
var lastUrlPc = urlPcs[urlPcs.length - 1];
return lastUrlPc.split('_')[0];
}
You can attribute the url to an 'A' element and use javascript's built in methods to make your life easier:
var parser = document.createElement('a');
parser.href = "YOUR URL HERE";
var fileName = parser.pathname.split('/').pop();
var code = fileName.split('_')[0];
code will have the value you want.
I would use a regular expression and sense it seems you are looking for numbers you can do the regex filter for that.
var path = window.location.pathname,
regFilter = /\d*/g,
filter = regFilter.exec(path);
The regular expression \d narrows your filter search to only look for digits. And the * grabs the group of digits.
Your result is in the filter var. The only thing about this is that the exec returns an array with your original string and the returned result which will be at the 1 index so you'll have to grab it from there like so.
filter[1];
Hi everybody this code is used to have a list name and id of facebook friends or invited friends if executed on friend list page. I'm trying to count the character of a string in javascript but .length method return always 1. I don't understand why cause I'm counting on a string not an array.
this is my code:
var name_list;
var id_list;
var count_letter_l;
var count_name = 0;
var count_id = 0;
var inputs = document.getElementsByClassName('_2akq _1box');
for(var i=0;i<inputs.length;i++){
var name = inputs[i].getElementsByTagName('span')[0].childNodes[0].nodeValue;
var full_id = inputs[i].getAttribute("data-reactid");
var split_id = full_id.split(':');
var split_two = split_id[1].split('.');
var split_final = split_two[0];
var count_letter = split_final.length;
//console.log(count_letter);
if(name != 'null'){
name_list+= ',' + '"' + name + '"';
id_list += ',' + '"' + split_final + '"';
count_letter_l += ',' + '"' + count_letter + '"';
count_name++;
count_id++;
}
}
console.log(name_list);
console.log('------!!!!!!!!------');
console.log(id_list);
console.log('names = ' + count_name);
console.log('id = ' + count_id);
console.log('letters for esch field = ' + count_letter_l);
I wish to count the character of every id cause in my case when I grab the ids I have some "0" and "1" in the and of the list. I don't know why and I wish to cut them out of the list.
This is an element of _2akq _1box class. you can see it if open firefox firbug and look at facebook front-end html code while you are displaying the friends list
<span class="_2akq _1box" data-reactid=".5q.2.0.0.0.0:0:1:$1543522353.0.0.$2.$text.0.0">
<span data-reactid=".5q.2.0.0.0.0:0:1:$1543522353.0.0.$2.$text.0.0.0">Laura Casali</span>
</span>
the console tell me:
letters for esch field = undefined,"1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1".....
tnx for help
I'm having a small problem with a regexp pattern. I don't have regexp knowledge, so I couldn't solve it.
I have this text:
var text = "this (is) some (ran)dom text";
and I want to capture anything between (). So after following this tutorial I came up with this pattern:
var re = /(\(\w*\))/g;
which works fine. But what I want to do now is replace the found matches, or rather modify. I want to wrap the found matches with a span tag. So I used this code:
var spanOpen = '<span style="color: silver;">';
var spanClose = '</span>';
text.replace(re, spanOpen + text.match(re) + spanClose);
even though the code works, I don't get the result I want. It outputs:
as HTML
this <span style="color: silver;">(is),(ran)</span> some <span style="color: silver;">(is),(ran)</span>dom text
as text
this (is),(ran) some (is),(ran)dom text
You can check the example in fiddle. How can I fix this?
The code in fiddle:
var text = "this (is) some (ran)dom text";
var re = /(\(\w*\))/g;
var spanOpen = '<span style="color: silver;">';
var spanClose = '</span>';
var original = "original: " + text + "<br>";
var desired = "desired: this " +spanOpen+"(is)"+spanClose+ " some " +spanOpen+"(ran)"+spanClose+ "dom text<br>";
var output = "output: " + text.replace(re, spanOpen + text.match(re) + spanClose);
var result = original + desired + output;
document.body.innerHTML = result;
If the title is wrong or misleading, I'll change it.
The .replace() method can take a function as the 2nd parameter. That will come in handy here.
var output = "output: " + text.replace(re, function(match){
return spanOpen + match + spanClose
});
The function will be called for each individual match.
You can also use '$&' in your replace string to reference each match
var output = "output: " + text.replace(re, spanOpen + '$&' + spanClose);
See: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/replace
text.match(re) is returning an array of the result, so what you can do is loop this array and replace your string with each items, like this:
var matches = text.match(re);
var output = "output: " + text;
for (var i = 0; i < matches.length; i++)
{
output = output.replace(matches[i], spanOpen + matches[i] + spanClose);
}
