javascript - jQuery check if two values is blank -



javascript - jQuery check if two values is blank -

i have 3 values:

var tbb = $("#total1 span").text(); var tmb = $("#total2 span").text(); var tab = $("#total3 span").text();

each of them blank.

what improve way in javascript/jquery check if 2 of these values blank?

update

here mean, bit ugly , "lot of lines" solution

var = 0; if (tab != "") { i++; } if (tmb != "") { i++; } if (tbb != "") { i++; } if (i >= 2) { //do }

any improve thoughts?

if(tbb == null || tbb == ''){...}

and same rest.

javascript jquery

string - what is the difference between "some" == "some\0" and strcmp("some","some\0") in c++? -

string - what is the difference between "some" == "some\0" and strcmp("some","some\0") in c++? - what difference between "some" == "some\0" , strcmp("some","some\0") in c++? why if("some" == "some\0") returns false , if(!strcmp("some","some\0")) returns true ? see next diagram. shows 2 strings in memory, content in box, beside box you'll see address of each one. when you're doing if("some" == "some\0") comparing addresses. translated if (0xdeadbeef == 0x0badcafe) false. when utilize strcmp , compare content of each box until reach \0 in each of them. that's why sec test returns true. if alter first test if("some" == "some") compiler may potentially see same strings , store them once. means test transform if (0x0badcafe == 0x0badcafe) true. c++ string comparison
