I have got a string with #! and i want to replace the #! with empty .
This is my code
$(document).ready(function () {
var uri = 'ghgfhf'
if (uri.indexOf("#") > 0) {
var clean_uri = removeURLParameter(uri);
console.log(clean_uri);
}
});
function removeURLParameter(url) {
url = url.replace(/!#/,'');
return url;
}
Could you please let me know how to replace the #! with empty ('')

"!#" should be "#!"
function removeURLParameter(url) {
url = url.replace(/#!/,'');
return url;
}

Hi I want to find text url in my editor and convert them to anchor tag links using jquery.
here is my code
function urlify(text) {
var urlRegex = /^(https?:\/\/)?([\da-z\.-]+)\.([a-z\.]{2,6})([\/\w \.-]*)*\/?$/;
return text.replace(urlRegex, function(url) {
return '' + url + '';
})
}
$("#queEditor").bind('input propertychange', function(){
var url = urlify($("#queEditor").text);
console.log(url);
});
But it's giving an error undefined function text. Could someone help me rectify this?

Since .text() is a function you need to use () when you want to invoke it.
$("#queEditor").text(); //Notice ()

I want to pass a value to a Javascript Statement. Is it possible?
For Example :
function Show(msg, Id, Msgtype) { // I need to pass this Id argument to below javascript innerHtml statement
var strVar = "";
strVar = "Hello" + Msgtype + " <i class='icon-remove close'></i> " + msg + "</div>";
document.getElementById("???").innerHTML = strVar; // ??? should be the Id above in the function arguments
}
Or in other way, how can I achieve this scenario?

Just pass Id, like this
document.getElementById(Id).innerHTML = strVar;

I want to make a function that has to generate a random number between 2 numbers and you can save it in a variable. I'm using this code:
function rand(ran1, ran2, randVar) {
var randomNumb = Math.floor(Math.random()*(ran2 - ran1)) + ran1;
eval("var " +randVar+ " = "+randomNumb+";");
}
rand(12, 49, rand1)
alert("Your number is: "+rand1)
The error I get is: Can't find variable: rand1
Can anyone help me?

Using eval for this is entirely unnecessary. I'd recommend something like this instead:
function rand(ran1, ran2) {
var randomNumb = Math.floor(Math.random()*(ran2 - ran1)) + ran1;
return randomNumb;
}
var rand1 = rand(12, 49);
alert("Your number is: " + rand1);
Notice that in calling the function, the only real difference is in where you place the identifier, rand1.

I'm trying to replace the src of an tag with another path. This works perfectly well:
var tempDocId = 'someId';
$('#documents' + that.ticketId).append('<img id="'+tempDocId+'" src="/img/support/pdf_icon.jpg">');
but the following code gives one of those "image not found" icons ():
var tempDocId = 'someId';
$('#documents' + that.ticketId).append('<img id="'+tempDocId+'" src="/img/support/loading.jpg">');
$('#tempDocId').attr("src", "/img/support/pdf_icon.jpg");
Does anybody know what I'm doing wrong here? All tips are welcome!

because you are looking for id="tempDocId", not the one you generated.
$('#tempDocId').attr("src", "/img/support/pdf_icon.jpg");
needs to be
$('#' + tempDocId).attr("src", "/img/support/pdf_icon.jpg");
so you are not replacing the source. My guess is that your loading image is not valid.

Because $('#tempDocId') doesn't exist. tempDocId is a variable, so try:
$('#' + tempDocId).attr('src', '/img/support/pdf_icon.jpg');

var tempDocId = 'doc' + Math.random().toString().substr(2);
var $img = $('<img id="'+tempDocId+'" src="/img/support/loading.jpg">');
$img.appendTo('#documents' + that.ticketId);
$img.attr('src', '/img/support/pdf_icon.jpg');
