LImit Java 脚本打印输出中的字符
LImit Characters in Java Script Print output
我正在尝试使用 js 文件限制打印在标签上的字符数。我遇到问题的代码部分由按钮调用,并从预览框中打印内容。除了我要打印的标题长度外,一切正常。每当我添加代码来限制我得到的字符数时:
类型错误:title.substring 不是一个函数
标题 = title.substring(0, 11);任何想法
// To allow for the TEMP SLU's to be printed from the main page in alpha order
$("#barcodesku").live('click', function(){
var title=[];
var sku=[];
var first = "";
var second = "";
var indexGlobal = 0;
$('#acctRecords tbody tr').each(function()
{
sku.push($(this).find('#tableSKU').html());
title.push ($(this).find('#tableTitle').html());
}); //end of acctRecords tbody function
//Print the bar codes
title = title.substring(0,16);
var x=0;
for (x=0;x<sku.length;x++){
first += '$("#'+indexGlobal+'").barcode("'+sku[x]+'", "codabar",{barHeight:40, fontSize:30, output:"bmp"});';
second += '<div class="wrapper"><img src="../images/temp.jpg" /><div id="'+indexGlobal+
'"></div><div class="fullSKU">      '+sku[x]+'</div><br/><div class="title", {title.substring(0,16)}; >'+title[x]+' </div></div><br/><br/>';
indexGlobal++;
}
var barcode = window.open('','BarcodeWindow','width=200');
var html = '<html><head><title>Barcode</title><style type="text/css">'+
'.page-break{display:block; page-break-before:always; }'+
'body{width: 2in;}'+
'.wrapper{height: 1in;margin-left:10px;margin-top:5px;margin-right:5px;}'+
'.fullSKU{float: left;}'+
'.shortSKU{float: right;font-size:25px;font-weight:bold;}'+
'.title{float: left;}'+
'</style><script type="text/javascript"src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.2/jquery.js"></script><script type="text/javascript" src="../barcode/jquery-barcode.js"></script><script>$(document).ready(function() {'+first+'window.print();window.close();});</script></head><body>'+second+'</body></html>';
barcode.document.open();

barcode.document.close();
}); // end of click function
从你的代码中我看到 title 是一个标题数组。您需要执行以下操作:
for (var i = 0; i < title.length; i++) {
title[i] = title[i].substring(0, 11);
}
