QuerySelector Examples

multiple items

document.querySelectorAll('div, span')

document.querySelectorAll('[data-example="test"]')

css pseudo class

document.querySelectorAll('#test li')

all table cells not right align

document.querySelectorAll(‘tbody td:not(.MuiTableCell-alignRight)’)

every other tr starting with first

querySelectorAll(‘tr:nth-of-type(2n+1)’)

input

<input type="checkbox" id="c2" name="c2" value="DE039230952"/>
//Replace $$ with document.querySelectorAll in the examples:

$$('input') //Every input
$$('[id]') //Every element with id
$$('[id="c2"]') //Every element with id="c2"
$$('input,[id]') //Every input + every element with id
$$('input[id]') //Every input including id
$$('input[id="c2"]') //Every input including id="c2"
$$('input#c2') //Every input including id="c2" (same as above)
$$('input#c2[value="DE039230952"]') //Every input including id="c2" and value="DE039230952"
$$('input#c2[value^="DE039"]') //Every input including id="c2" and value has content starting with DE039
$$('input#c2[value$="0952"]') //Every input including id="c2" and value has content ending with 0952
$$('input#c2[value*="39230"]') //Every input including id="c2" and value has conten

//Use the examples above directly, without the need for additional library, just by adding:

const $$ = document.querySelectorAll.bind(document);
//Some additions:

$$(.) //The same as $([class])
$$(div > input) //div is parent tag to input
document.querySelector() //equals to $$()[0] or $()
