Days using jquery to get the value of the Background-color in the style found that the color value in IE is not the same as the Chrome, Firefox display format, ie in the hex format display #ffff00, and Chrome, Firefox is in the GRB format to display RGB (255,0,0), because the need to store color values in the database, so you want to make the color value of the format unified (in fact, is not unified also can be saved). Search for a bit, from a foreign website to get a section of code
Copy Code code as follows:
$.fn.gethexbackgroundcolor = function () {
var RGB = $ (this). CSS (' Background-color ');
RGB = Rgb.match (/^rgb (d+), s* (d+), s* (d+)) $/);
function Hex (x) {return ("0" + parseint (x). toString). Slice (-2);}
return rgb= "#" + Hex (rgb[1]) + hex (rgb[2]) + hex (rgb[3));
}
Solutions
The above definition is a jquery function that we can pass $ ("#bg"). Gethexbackgroundcolor (); Gets the RGB value of the Background-color of the label id= "BG"
Below do a little modification, is to add a judgment, if it is IE browser directly to get the value, if the non-IE browser will convert the value to RGB format:
Copy Code code as follows:
$.fn.gethexbackgroundcolor = function () {var RGB = $ (this). CSS (' Background-color '); if (!$.browser.msie) {RGB = Rgb.match (/^rgb\ (\d+), \s* (\d+), \s* (\d+) \) $/); function Hex (x) {return ("0" + parseint (x). toString). Slice ( -2);} rgb= "#" + Hex (rgb[1)) + hex (rgb[2)) + hex (rgb[3)); } return RGB; }
