I am trying to find a word in the text with my name. The code requires me to first find the first character of the word and then subsequently push the remaining letters in the hits[] array. I am trying but got stuck.
var text = "This is just Rohit.";
var myName = "Rohit";
var hits = [];
for (var i = 0; i < text.length; i++)
{
if(text[i] === myName[0] )
{
for(j = 0; j < myName.length; j++)
{
hits.push(text[i]);
};
};
};
hits;
var text = "This is just Rohit.";
var myName = "Rohit";
var hits = [];
for (var i = 0; i < text.length; i++) {
if(text[i] === myName[0] ) {
for(var j = i, l = 0; l < myName.length; j++, l++) {
hits.push(text[j]);
}
}
}
console.log(hits.join(''));
Just ignore the searchtext and go with the searchterm.
var hits = [];
var i=0;
while (i<"Rohit".length) arr.push("Rohit"[i++]);
console.log(hits);
// ["R", "o", "h", "i", "t"]
Something like this should help.Let me know if a change is needed.
var text = "This is just Rohit.";
var myName = "Rohit.";
var hits = [];
var array1=text.split(" ");
for (var i = 0; i < array1.length; i++)
{
if(array1[i]==myName)
{
hits.push(array1[i].split(''));
}
}
THIS PART IS THE METHOD WHICH YOU WERE USING::
var text = "This is just Rohit.";
var myName = "Rohit";
var hits = [];
var x='';
for (var i = 0; i < text.length; i++)
{
if(text[i] === myName.charAt(0) && text[i-1]==" " )
{
for(j = i; j < (i+myName.length); j++)
{
console.log(text[j]);
x=x+text[j];
}
}
}
hits[0]=x;
alert(hits);
After looking at your comments for clarification, it looks like you just want your name as the only element in a new array.
Use this:
var text = 'Your name is Rohit.';
var name = 'Rohit';
var hits = [text.substring(text.indexOf(name), text.indexOf(name) + name.length)];
console.log(hits);
// ["Rohit"]
Can't imagine how this is helpful, but the code above will do what you want.
I solved it.
var text = "This is just Rohit.";
var myName = "Rohit";
var hits = [];
for (var i = 0; i < text.length; i++)
{
if(text[i] === myName[0] )
{
for(var j = i; j < (myName.length+i); j++)
{
hits.push(text[j]);
};
};
};
hits;

I have a string that I am trying to loop through. It has nested arrays and I want to get the values from each layer. However I seem to be getting an undefined from the second layer onwards.
//String [{"username":"test","usersurname":"test","cellnumber":"test","displayname":"test","profilepicture":"test","projects":[{"projectname":"test","dateadded":"test","notes":"test","image":"test"},{"task":[{"taskname":"test","taskdescription":"test","taskimage":"test"}]}]}]
//My for loop - All variables are declared prior
for(var i = 0; i < data.length; i++){
username = data[i].username;
console.log(username);
usersurname = data[i].usersurname;
cellnumber = data[i].cellnumber;
displayname = data[i].displayname;
profilepicture = data[i].profilepicture;
for(var j = 0; j < data[i].projects.length; j++){
dateadded = data[i].projects[j].dateadded;
console.log(dateadded);
notes = data[i].projects[j].notes;
image = data[i].projects[j].image;
for(var k = 0; k < data[i].projects[j].task.length; k++){
taskname = data[i].projects[j].task[k].taskname;
console.log(taskname);
taskdescription = data[i].projects[j].task[k].taskdescription;
taskimage = data[i].projects[j].task[k].taskimage;
}
}
}
Please check undefined end errors in your code. if something is undefined loop will break.
for (var i = 0; i < data.length; i++) {
username = data[i].username;
console.log(username);
usersurname = data[i].usersurname;
cellnumber = data[i].cellnumber;
displayname = data[i].displayname;
profilepicture = data[i].profilepicture;
if("undefined" != typeof (data[i].projects))
{
for (var j = 0; j < data[i].projects.length; j++) {
dateadded = data[i].projects[j].dateadded;
console.log(dateadded);
notes = data[i].projects[j].notes;
image = data[i].projects[j].image;
if ("undefined" != typeof (data[i].projects[j].task)) {
for (var k = 0; k < data[i].projects[j].task.length; k++) {
taskname = data[i].projects[j].task[k].taskname;
console.log(taskname);
taskdescription = data[i].projects[j].task[k].taskdescription;
taskimage = data[i].projects[j].task[k].taskimage;
}
}
}

Our developer used this phone number 1-866-579-469 all over the website but the correct phone number is 1-866-579-4269. I have written a javascript function to replace all occurrences:
var nodes,currentElement,oldtext,newtext,replaced,count;
function replaceAll(nodes,oldtext,newtext,replaced) {
count = 0
for (var i = 0; i < nodes.length; i++) {
currentElement = nodes[i].innerHTML;
replaced = currentElement.replace(oldtext,newtext);
count++;
}
console.log("Edited: "+ count + " items");
}
oldtext = "1-866-579-469";
newtext = "1-866-579-4269";
nodes = document.getElementsByTagName('*');
replaceAll(nodes,oldtext,newtext,replaced);
Your code works but you missed to update the replaced string. This should work:
var nodes,currentElement,oldtext,newtext,replaced,count;
function replaceAll(nodes,oldtext,newtext,replaced) {
count = 0
for (var i = 0; i < nodes.length; i++) {
currentElement = nodes[i].innerHTML;
replaced = currentElement.replace(oldtext,newtext);
nodes[i].innerHTML = replaced;
count++;
}
console.log("Edited: "+ count + " items");
}
oldtext = "1-866-579-469";
newtext = "1-866-579-4269";
nodes = document.getElementsByTagName('*');
replaceAll(nodes,oldtext,newtext,replaced);

I am working on this table that as to be managed by the client. I want to know if is possible to change the color of the entire row when in the "Status" column he writes the word "vermietet".
In this case when the client write "vermietet" the rows that contains that word change background color in orange.
Any JS tips?
Thanks in adivce.
EDIT:
I tried this
<script>
jQuery(document).ready(function($){
$(document.body)var cols = document.getElementsByClassName('column-10');
for (var i = 0; i < cols.length; ++i) {
var col = cols[i];
if (col.innerHTML === 'vermietet') {
var parent = col;
while((parent = parent.parentElement).tagName !== 'TR');
var found = parent.childNodes;
for (var j = 0; j < found.length; ++j) {
var td = found[j];
if (td.tagName === 'TD') {
td.style.backgroundColor = 'orange';
}
}
}
}
});
</script>
Pure JS solution:
var cols = document.getElementsByClassName('column-10');
for (var i = 0; i < cols.length; ++i) {
var col = cols[i];
if (col.innerHTML === 'vermietet') {
var parent = col;
while((parent = parent.parentElement).tagName !== 'TR');
var found = parent.childNodes;
for (var j = 0; j < found.length; ++j) {
var td = found[j];
if (td.tagName === 'TD') {
td.style.backgroundColor = 'orange';
}
}
}
}
abc1 abc2 abc3

using above csv file, load text by replacing the double quotes from the bellow sentence.
Sentence:
"" is going with "" to "" for something to know.
Expected out put is:
abc1 is going with abc2 to abc3 for something to know.
abc3 is going with abc5 to abc6 for something to know.
like this in javascript, php.
Code I have tried so far:
var s = 'Neque porro "" estqui "" dolorem';
var insert = [["a1", "b1"]["c1","d1"]];
console.log(insert);
var words = new Array();
words = s.split(" ");
console.log(words);
var count = 0;
for (i = 0; i < words.length; i++) {
for (j = 0; j < insert.length; j++) {
if(words[i] == '""')
s = s.replace(/""/, insert[j]);
}
}
console.log(s);
Hurray I got the answer:
reader.onload = function (e) {
var sent = ''; var sentt = ''; var senttt = '';
sent = $('#mixmsg').val();
var quoteLength = (sent.match(/""/g) || []).length;
var rowcells = [];
rows = e.target.result.split("\n"); alert(rows);
for (var i = 0; i < rows.length; i++) {
var cells = rows[i].split(",");
rowcells.push(cells);
}
var rowcellso = rowcells.slice(0, -1);
console.log(rowcellso);
for (var ro = 0; ro < rowcellso.length; ro++) {
for (var scol = 0; scol < quoteLength; scol++) {
sent = sent.replace(/""/,rowcellso[ro][scol]);
console.log(rowcellso[ro][scol]);
} sentt +=sent+'\n'; sent= $('#mixmsg').val();
}
$('#container').html(sentt);
}
I want to create a Javascript array of words, then use Javascript to find the longest word and print it to the screen. Here is my code:
var StrValues = []
StrValues[0] = ["cricket"]
StrValues[1] = ["basketball"]
StrValues[2] = ["hockey"]
StrValues[3] = ["swimming"]
StrValues[4] = ["soccer"]
StrValues[5] = ["tennis"]
document.writeln(StrValues);
You can use length to find the longest string in a array. Here is a fiddle http://jsfiddle.net/2sebnb33/1/
for(var i=0;i<StrValues .length;i++){
if(StrValues [i].length>len){
len=StrValues [i].length;index=i;}
}
var strValues = ["cricket", "basketball", "hockey"];
var max = '';
for(var i = 0; i< strValues.length; i++) {
max = strValues[i].length > max.length ? strValues[i] : max;
}
alert(max);
Firstly, you need to correct the way you are creating array.
For instance, it should be like this
var StrValues = [];
StrValues[0] = ["cricket"];
The logic
var longestWord = "";
for (var i = 0 ; i < StrValues.length; i++) {
if(StrValues[i].length > longestWord.length) {
longestWord = StrValues[i];
}
}
See the code below:
var array = [];
array.push("cat");
array.push("children");
array.push("house");
array.push("table");
array.push("amazing");
var maxSize = 0;
var maxSizeWord = "";
for(var i = 0; i < array.length; i++) {
if (maxSize < array[i].length) {
maxSize = array[i].length;
maxSizeWord = array[i];
}
}
alert("The biggest word is '" + maxSizeWord + "' with length '" + maxSize + "'!");
