[英]Background color change from form field
I need to create a form with the ability to let the user input a hex value, then upon click it applies that color. 我需要创建一个能够让用户输入一个十六进制值的表单,然后单击该表单即可应用该颜色。 I have it working in firefox unless there is a background image already chosen, and it won't work in IE at all(surprise surprise) I think I need to have the background image removed first.
除非已经选择了背景图片,否则我将它在firefox中工作,并且它根本不会在IE中工作(惊讶),我想我需要先删除背景图片。 This is what I have so far
这就是我到目前为止
script 脚本
$("#newBodyColorBtn").click(function() {
$("body").css("background-color", $("#newBodyColor").val());
});
Form code 表格代码
<form action="#" method="get" name="putcolor">
<strong>Put your color value here</strong> <input id="newBodyColor" type="text" value="" size="15">
<button id="newBodyColorBtn">Change Body Color</button>
</form>
