Is there a way to only match the character "=" in a string if it is not at the beginning of a line and no other character, for example "$", appears on the same line?
Just to clarify, in the examples below:
$a = b
a
= b
a = b
I am only interested in matching the equal sign in the last line.
This particular solution should work
/^[^$]+=[^$]+$/
This regular expression will find patterns that consist of 1 or more characters that are not the dollar sign ($), followed by an equal sign, and then 1 or more characters that are not the dollar sign ($).
var test = [
'$a = b',
'a',
'= b',
'a = b',
];
console.log(test.map(function (a) {
return a+' :'+/^[^$]+=[^$]+$/.test(a);
}));For instance, You have two JSON files: Json file #1: [{colorname:blue},{colorname:blue}] Json file #2: [{colorname:red},{colorname:red}] Within the controller, there exists a variable called $scope.color In the HTML code, there are two buttons named " ...
