How do you pass a variable to a Regular Expression JavaScript?
This is my regexp
regexp:{
spamcheck : /^[15]+$/
}
I need to do this
var spamcheck_sum = 15;
regexp:{
spamcheck : /^[spamcheck_sum]+$/
}
and
Side note: I cant use my spamcheck_sum var outside the js reason is my js file loads first and my var for sum loads after , any way to globalize that var to be acceptable no matter if js file loads first?

jQuery selectors with variables
(5 answers)
Closed 2 years ago.
I am very new to jQuery but learning. I am trying to do something simple (I think) but struggling. I am trying to add a var into Jquery to customise an specific element.
I need to add 'styler' class to my div which has the id="spinner7" like -
$('#spinner7').addClass('styler');
However the number can vary so I need to add it to the end of #spinner. I have tried things like below but no joy. Can anyone help please.
var ctrl = '7';
$('#spinner +ctrl').addClass('styler');
Template literals
var ctrl = '7';
$(`#spinner${ctrl}`).addClass('styler');
Or
var ctrl = '7';
$('#spinner' + ctrl).addClass('styler');

I'm trying to retrieve the value of my setAttribute into my javascript code but I get a syntax error when I run the page.
Here is the code of my setAttribute in my servlet:
request.setAttribute("codeIGA", codeIGA); //a string is being passed here
Here is the code of my JS:
$(document).ready(
function () {
var count = 0;
var lastCodeIGA = ${sessionScope.codeIGA}; // syntax error here
console.log(lastCodeIGA);
.
.
.
etc
How can I retrieve the value from my servlet and input it into my JS?
You can use following to retrieve the required value.
var lastCodeIGA = '${codeIGA}';
Try with scriptlet.
var test = <%=request.getAttribute("codeIGA");
Or
var lastCodeIGA = '${codeIGA}';

Encoding Javascript Object to Json string

Closed 6 years ago.
SORRY! EDIT ON OLD BROWSERS prior to ie8!
In order to create XML on the fly in JS, one can do the below,
Is there any way I can achieve the same - creating JSON on the fly in JS without the use of any external library?
var parent = document.createElement("parent");
var children = document.createElement('children');
var child1 = document.createElement('child1');
var child2 = document.createElement('child2');
var textNode1 = document.createTextNode("some text1");
var textNode2 = document.createTextNode("some text2");
child1.appendChild(textNode1 );
child2.appendChild(textNode2 );
children.appendChild(child1);
children.appendChild(child2);
parent.appendChild(children);
alert(parent.outerHTML);
Just use JSON.stringify()
i.e.
var o={a:12};
JSON.stringify(o);
results in
"{"a":12}"

Encode URL in JavaScript
(22 answers)
Closed 8 years ago.
I want to load another page via Javascript like this
$("#resultarea").load("searchresults.php?searchstring=" + $("#searchbox").val());
in searchresults.php, a single statement
echo $_GET["searchstring"];
what I type in searchbox appears when searchresults.php is loaded except when I add space and another word, no thing appear at all. I heared it can be done by encoding or somewhat, I searched but didn't find a solution.
Try encodeURIComponent:
var encodedValue = encodeURIComponent($("#searchbox").val());
$("#resultarea").load("searchresults.php?searchstring=" + encodedValue);
