我似乎无法进一步了解这一点。我更像是一个图形人而不是程序员 每次按下按钮时,我都需要一个按钮,从白色到灰色再到红色再到黑色再到白色。一个pdf文件中将有超过一百个这样的按钮 这是我到目前为止所尝试的:
if (this.getField("Button1").fillColor = ["RGB",1,1,1])
{
app.alert({ cMsg: "Switch to Grey", });
this.getField("Button1").fillColor = ["RGB",.5,.5,.5];
};
if (this.getField("Button1").fillColor = ["RGB",.5,.5,.5])
{
app.alert({ cMsg: "Switch to Red", });
this.getField("Button1").fillColor = ["RGB",1,0,0];
};
if (this.getField("Button1").fillColor = ["RGB",1,0,0])
{
app.alert({ cMsg: "Switch to Black", });
this.getField("Button1").fillColor = ["RGB",0,0,0];
};
if (this.getField("Button1").fillColor = ["RGB",0,0,0])
{
app.alert({ cMsg: "Switch to White", });
this.getField("Button1").fillColor = ["RGB",1,1,1];
};
这可能吗? 感谢

使用您自己的代码,它看起来像这样:
if (this.getField("Button1").fillColor == ["RGB",1,1,1])
{
app.alert({ cMsg: "Switch to Grey", });
this.getField("Button1").fillColor = ["RGB",.5,.5,.5];
}
else if (this.getField("Button1").fillColor == ["RGB",.5,.5,.5])
{
app.alert({ cMsg: "Switch to Red", });
this.getField("Button1").fillColor = ["RGB",1,0,0];
}
else if (this.getField("Button1").fillColor == ["RGB",1,0,0])
{
app.alert({ cMsg: "Switch to Black", });
this.getField("Button1").fillColor = ["RGB",0,0,0];
}
else if (this.getField("Button1").fillColor == ["RGB",0,0,0])
{
app.alert({ cMsg: "Switch to White", });
this.getField("Button1").fillColor = ["RGB",1,1,1];
}
我以前的答案 :(仅供参考)
下面的内容纯粹是针对JavaScript和HTML而不是PDF,但您将了解它是如何完成的。
您可以在JavaScript中使用getElementById
和rgb
,如:
document.getElementById("button1").style.backgroundColor == "rgb(0, 255, 0)"
我将在这里举一个例子。假设你有一个蓝色的按钮,如
<div>
<button id="button1" onclick="getcolor()" style="background-color:#0000FF; padding:5px;">Colored Button - Blue</button>
</div>
我们希望将其更改为绿色,如果是绿色我们想将其更改为蓝色,那么您将拥有这样的JavaScript:
function getcolor()
{
var button_color = document.getElementById("button1").style.backgroundColor;
if (button_color == "rgb(255, 255, 255)")
{
alert("Switch color to Grey");
document.getElementById("button1").style.backgroundColor = "rgb(128, 128, 128)";
}
else if (button_color == "rgb(128, 128, 128)")
{
alert("Switch color to Red");
document.getElementById("button1").style.backgroundColor = "rgb(255, 0, 0)";
}
else if (button_color == "rgb(255, 0, 0)")
{
alert("Switch color to Black");
document.getElementById("button1").style.backgroundColor = "rgb(0, 0, 0)";
}
else if (button_color == "rgb(0, 0, 0)")
{
alert("Switch color to White");
document.getElementById("button1").style.backgroundColor = "rgb(255, 255, 255)";
}
}
顺便说一下小心rgb中的空格比较例如蓝色时比较它不应该是rgb(0,0,255),它在颜色的每个十进制值之后没有空格,如:
if (button_color == "rgb(0,0,255)")
但它应该是这样的:
if (button_color == "rgb(0, 0, 255)")
