[Solved] Parse string using javascript [closed]

by


You can find the pos of the “He ” using the indexOf method and then get the position of the next line-break to remove that line using the substring method.

var someString = "Hello world,\n" +
    "He like cats and dogs\n" +
    "Bye bye";

var pos = someString.indexOf('He ');
var nextLineBreak = someString.indexOf('\n', pos);

var firstPart = someString.substring(0, pos);
var secondPart = someString.substring(nextLineBreak +1);

var finalString = firstPart + secondPart;
alert(finalString);
