Question

我正在使用dymo打印机，这是他们提供的用于启用网页打印的代码。我编辑它有3个文本框，所以我可以一次打印3个标签。我的问题是：当我按下打印按钮时，它只打印第一个文本框。

我需要打印所有3个测试盒。此外，如果可以编辑代码，如果其中一个框留空，则脚本将跳过该代码并仅打印包含文本的文本框。

在这里烦恼是PrintLable.js

Answer 1

您需要在以下行中创建一些javascript函数。

var process_labels = function(label_DOM_element){

        var textTextArea = label_DOM_element.getElementById('textTextArea');  

        print_label(textTextArea);
}

然后你需要将标签JS更改为一个函数，它是一个触发而不是加载到body load上的函数。你还需要允许传入params。

所以而不是

// prints the label printButton.onclick = function()

将此更改为类似的函数：

 var print_label = function(textTextArea){
       {
                // open label
                var labelXml = '<?xml version="1.0" encoding="utf-8"?>\
    <DieCutLabel Version="8.0" Units="twips">\
        <PaperOrientation>Landscape</PaperOrientation>\
        <Id>Address</Id>\
        <PaperName>30252 Address</PaperName>\
        <DrawCommands/>\
        <ObjectInfo>\
            <TextObject>\
                <Name>Text</Name>\
                <ForeColor Alpha="255" Red="0" Green="0" Blue="0" />\
                <BackColor Alpha="0" Red="255" Green="255" Blue="255" />\
                <LinkedObjectName></LinkedObjectName>\
                <Rotation>Rotation0</Rotation>\
                <IsMirrored>False</IsMirrored>\
                <IsVariable>True</IsVariable>\
                <HorizontalAlignment>Left</HorizontalAlignment>\
                <VerticalAlignment>Middle</VerticalAlignment>\
                <TextFitMode>ShrinkToFit</TextFitMode>\
                <UseFullFontHeight>True</UseFullFontHeight>\
                <Verticalized>False</Verticalized>\
                <StyledText/>\
            </TextObject>\
            <Bounds X="332" Y="150" Width="4455" Height="1260" />\
        </ObjectInfo>\
    </DieCutLabel>';

ETC ETC... 
}

我不会为你写完整件事，但基本上你会有一个按钮点击功能，它会检查'textDiv'的所有元素并将它们传递给process_label函数。

有一些工作涉及但你的javascrtipt目前只期望1个元素，所以你需要创建一个可以按需调用的函数。

这是我打印多个标签的代码。我已经为您的帮助添加了评论。请仔细阅读，如果您有任何疑问请问我。我不能在此处提供我的HTML供您参考。
