var inkmax = document.getElementById("spreadrateinput");
var times = document.getElementById("spreaddegreeinput");
console.log(inkmax.value);
console.log(times.value); 1 : javascript is triggered, and consloe statements are not executed when you enter data;
2 : you can use onblur to trigger events when input loses focus;
3 : if it is submitted to the background, submit in the form of form form, try not to use getvalue, the security is poor;
< input type= "text" id= "spreadrateinput" onChange= "changeFunction ()" / >
< input type= "text" id= "spreaddegreeinput" onChange= "changeFunction ()" / >
changeFunction () {
var inkmax = document.getElementById ('spreadrateinput');
var times = document.getElementById (' spreaddegreeinput');
console.log (inkmax.value);
console.log (times.value);
}
