So im running this script and i want to be able to save the variable stopNumber after the script is finished running so that the next time i run this script the saved variable stopNumber can be set to the variable loops so that i dont have to manually set it all the time.

var loops = Number(prompt("Starting csv line?"));
var stopNumber = loops + 15;

for (csvLine = loops ; csvLine <= stopNumber ; csvLine++) {

iimSet ("-var_CSVLINE", csvLine);
iimPlay("Testing.iim");

}

回答1:

You can store the value in local storage

localStorage.setItem("stopNumber", stopNumber);

Retrieve it with

stopNumber = parseInt(localStorage.getItem("stopNumber"));

回答2:

try to use localStorage.

Like: localStorage.stopNumber = stopNumber;

you may call it as localStorage.stopNumber

Try this:

function doSomething() {
    var loops = doSomething.stopNumber || Number(prompt("Starting csv line?"));
    doSomething.stopNumber || doSomething.stopNumber = loops + 15;

    for (csvLine = loops ; csvLine <= stopNumber ; csvLine++) {

    iimSet ("-var_CSVLINE", csvLine);
    iimPlay("Testing.iim");

    }
}
