Why my javascript Comparison Operators code working incorrect ?
On this code requests_withdraw is 300 and money is
1200.34 but when i tested code it's will alert not enough money for withdraw Why ? how can i do ?
<script>
reqests_withdraw = "300";
money = "1200.34";
if(reqests_withdraw > money)
{
alert("not enough money for withdraw");
}
else
{
alert("OK");
}
</script>You are comparing string not numbers
Remove the double quotes
reqests_withdraw = 300;
money = 1200.34;
if (reqests_withdraw > money) {
alert("not enough money for withdraw");
} else {
alert("OK");
}you are comparing strings in your code, you need to use parseFloat()
<script>
reqests_withdraw = "300";
money = "1200.34";
if(parseFloat(reqests_withdraw) > parseFloat(money))
{
alert("not enough money for withdraw");
}
else
{
alert("OK");
}
</script>
Above have already been answered, but as an option, another way to turn a string into a number
reqests_withdraw = "300";
money = "1200.34";
if(+reqests_withdraw > +money)
{
alert("not enough money for withdraw");
}
else
{
alert("OK");
}
Yo have string there and it compares first letter. if there are equal it compare second letter.
"330.23">"340"
false
"330.23">"240"
true
"330.23">"2040"
true
to use them in if statement convert values to float using parseFloat
