Your question still isn’t explained very well, but I think I have it.<\/p>\n

You’re asking why this returns true:<\/p>\n

if($(this).html().indexOf(\"Title A\") != -1) {\n    \/\/should get here\n}\n<\/code><\/pre>\n
But this doesn’t:<\/p>\n
var titles = [\"Title A\"];\nvar realTitle = $(this).html();\nif (titles.indexOf(realTitle) > -1) {\n    \/\/should get here\n}\n<\/code><\/pre>\n
The difference has to do with the difference between string.indexOf()<\/code> and array.indexOf()<\/code>.<\/p>\n
string.indexOf()<\/code> searches for the specified text anywhere in the string. <\/p>\n
array.indexOf()<\/code> searches for the specified object (doesn’t have to be a string) anywhere in the array. <\/p>\n
Edit<\/strong> From your picture, I can see that your span contains a lot of whitespace. Try changing to this:<\/p>\n
var realTitle = $.trim($(this).text());\n<\/code><\/pre>\n
Edit 2<\/strong> in response to your comment:<\/p>\n
In that case, you’ll need to iterate the array and do indexOf<\/code> on each item. I think this is what you want:<\/p>\n
var realTitle = $.trim($(this).text());\n\nfor (var i = 0; i < titles.length; i++) {\n    if (realTitle.indexOf(titles[i]) > -1) {\n        $(this).parent().parent().parent().parent().css(\"background\", colorBackground);\n        $(this).parent().parent().parent().parent().find(\".row1\").css(\"background\", colorBackground);\n        $(this).parent().parent().parent().parent().find(\".row2\").css(\"background\", colorBackground);\n        break;\n    }\n}\n<\/code><\/pre>\n<\/p><\/div>\n
<\/div>\n<\/div>\n
