This article mainly introduces JS to get the background color of the Web page and font color method, the need for friends can refer to the following
Get the background color and font color of the Web page, as follows: thought: By obtaining the color property is worth to the RGB color, is not what we want, so you need to change the RGB color to hexadecimal color, first get RGB color: code as follows: Var r GB = document.getElementById (' color ') .style.backgroundcolor; get format as follows: RGB (225, 22, 23); Then split the: code as follows: var RGB = Rgb.split (' (') [1];//[RGB, 225,22,23)] in the form of a 2-length array The (225,22,23) string is split (note : Only the number type can be converted, so use parseint to cast the type! The: code is as follows: for (var k = 0; k < 3; k++) { str[k] = parseint (RGB. Split (', ') [K]). toString;//str array save split data &n Bsp } Final Combo: code as follows: str = ' # ' +str[0]+str[1]+str[2]; The entire code follows: code as follows: <! DOCTYPE html> <html> <head> <title>gethexcolor js/jquery get hexadecimal color </title > <meta charset= "Utf-8"/> <script type= "Text/javascript" > function Gethexbgcolor () { var str = []; var RGB = document.getElementById (' color '). Style.backgroundColor.split (' ('); for (var k = 0; K < 3; k++) { Str[k= parseint (Rgb[1].split (', ') [K]). toString; } str = ' # ' +str[0]+str[1]+str[2]; document.getElementById (' Color '). InnerHTML = str; } function gethexcolor () { var str = []; var RGB = document.getElementById (' color '). Style.color.split (' ('); for (var k = 0; k < 3; k++) { str[k] = parseint (r Gb[1].split (', ') [K]). toString; } str = ' # ' +str[0]+str[1]+str[2]; document.getElementById (' Color '). InnerHTML = str; } </script> <style type= "text/css" > #color { Width: 200px; height:200px; line-height:200px; text-align:center; } </style> < /head> <body> <div style= "color: #88ee22; Background-color: #ef8989; "id=" Color "></div> <input onclick=" Gethexbgcolor (); "Type= Button" value= "Get background color"/> <input onclick= Gethexcolor (); "type=" button "value=" Get font Color "/> </body> </HTml> Start building with 50+ products and up to 12 months usage for Elastic Compute Service
