Question

here is my javascript array alert(Parameter); it alerts:

Eqt_Param0=4.00,Eqt_Param1=0,Eqt_Param2=0

Now what I am trying to do is if any of the array elements values are equal to ‘0` i need to alert ‘array does not contain all values,’, so how to check whether array is empty or not.

Answer 1

It looks like your array is a set of values of the form “key=number”, and you want to know if any of the numbers are equal to zero.

The “proper” way to do it is:

var l = Parameter.length, i;
for( i=0; i<l; i++) {
    if( Parameter[i].split("=")[0] == "0") {
        alert("Array does not contain all values");
        break;
    }
}

But you could just hax it:

if( (Parameter.join(",")+",").indexOf("=0,") > -1) {
    alert("Array does not contain all values");
}
