Here is the line of code I am trying to target: <img class="pi" src="/graphics/ni/ni90.jpg" alt="Awaiting image">
I'm trying to select all of the images that have the attribute alt="Awaiting image"
If I try document.querySelectorAll("img.pi");
I will get all of the images that have the class pi
If I try document.querySelectorAll("img.pi[alt="Awaiting image"]");
I will get the error:Uncaught SyntaxError: missing ) after argument list
What is it that I am missing here?

The " used to delimit the value in the attribute selector are clashing with the " used to delimit the JS string literal.
document.querySelectorAll("img.pi[alt="Awaiting image"]");
^ ^^
| |Error
| End of string
Start of string
Use a different kind of quote.
document.querySelectorAll('img.pi[alt="Awaiting image"]');

Hi im pretty sure what im about to post might not be enough info (if so please let me know what more is needed). I am using node js and having a really weird error. Below is the code and output.
if (currentPrice > variableData[i].stopLossHard) {
console.log('if')
console.log(currentPrice)
console.log('is more than')
console.log(variableData[i].stoplossHard)
}
Output:
if
92.7
is more than
93.62700000000001
This is consistently happening. I also made sure that both currentPrice and variableData[i].stopLossHard are numbers and not strings (I made sure in the code and in the output its the color of a number not a string)
Any ideas is highly appreciated.

The attribute you print is different than the one you check in the if statement:
(In the if stopLossHard has a capital L, stop-L-ossHard, what you print doesn't)
Try this:
if (currentPrice > variableData[i].stoplossHard) {
console.log('if')
console.log(currentPrice)
console.log('is more than')
console.log(variableData[i].stoplossHard)
}

Here is the button code:
<button class="ncss-btn-black fs16-sm ncss-brand pb3-sm pl5-sm pr5-sm pt3-sm mr3-sm u-uppercase css-1n4ymyz" data-test="qa-cart-checkout">Checkout</button>
I have tried the following;
document.querySelector("button[data-test='qa-cart-checkout']”).click();
But I get the following error;
Uncaught SyntaxError: Invalid or unexpected token
What am I doing wrong? Please help, thanks.
I need the answer in modern dom or jquery.

It works fine as long as you use "normal" single and double quotes, not backticks or "smart quotes":
document.querySelector("button[data-test='qa-cart-checkout']").click();
<button class="ncss-btn-black fs16-sm ncss-brand pb3-sm pl5-sm pr5-sm pt3-sm mr3-sm u-uppercase css-1n4ymyz" data-test="qa-cart-checkout" onclick="alert('it works')">Checkout</button>

In Javascript a Backtick means template literals.

use regular ' or "

i have a objectId on my mvc model which i want to sent to a mvc API call, which results in a
"Uncaught SyntaxError: Invalid or unexpected token"
<script>
$(function () {
$('.btn-saveshedule').click(function () {
var selectedValue = $("#sel1 option:selected").val();
var userid =#Model.Id.ToString();
var json = getTimeSlotsInJson($('.schedule'), userid.str, selectedValue);
});
});
</script>
how on earth do i convert #Model.Id to a string?

You just need to put single quotes around it:
var userid ='#Model.Id.ToString()';

So, me and a few friends are making a text adventure in JavaScript. in it, there is a possibility of the player using a heal spell, which runs the following code:
function heal() {
alert('You chant some ominous-sounding words, and your wounds heal');
alert('Hit points restored!');
hitPoints += 60;
blobsOfDoom -= 30;
burn();
MonsAtt();
Choose Spell();
}
Error Messages:
Firefox:
/*
Exception: SyntaxError: missing ; before statement
#Scratchpad/1:2703
*/
Chrome:
SyntaxError: Unexpected identifier.
Why is this error showing up? How do I fix it?

You cant have spaces in functions
Choose Spell();
Check your function declaration for ChooseSpell and any other occurances, and change them to a valid function name, like chooseSpell()
