㈠ js如何实现list循环的结果不换行
问题不明确,想不换行的话,提供你一个思路吧
把每次从list取出来的数据编辑在一个变量里,然后使用编辑后的变量。
12345678var strOne;var strAll;for (i=0......){    strOne =list(i);    strAll =strAll + strOne;}代码可能有问题,但是大体这个意思。最后把strAll传出去
㈡ js得到的数据如何打印出来
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>打印测试</title>
</head>
<body>
<div id="printDIV">打印内容放在这</div>
<script type="text/javascript" language="javascript">
var str = document.getElementById("printDIV").innerHTML;
var printWin=window.open("打印窗口", "_blank");
printWin.document.write(str );
printWin.document.close();
printWin.print();
printWin.close();
</script>
</body>
</html>
㈢ js打印问题,急!!!!!
对JS的打印方法总结一下,方便日后查阅。
一.用JS自带函数打印
直接调用
Java代码 复制代码
   1. <a href="javascript:window.print();">打印</a> 
<a href="javascript:window.print();">打印</a>
二.IEWebBrowser组件
介绍
http://support.microsoft.com/default.aspx?scid=kb%3BEN-US%3BQ267240#top
http://support.microsoft.com/kb/q247671/#appliesto
Java代码 复制代码
   1. <OBJECT classid=CLSID:8856F961-340A-11D0-A96B-00C04FD705A2 height=0 id=WebBrowser width=0></OBJECT>   
   2. <input name=Button onClick=document.all.WebBrowser.ExecWB(1,1) type=button value=打开> 
   3. <input name=Button onClick=document.all.WebBrowser.ExecWB(2,1) type=button value=关闭所有> 
   4. <input name=Button onClick=document.all.WebBrowser.ExecWB(4,1) type=button value=另存为>   
   5. <input name=Button onClick=document.all.WebBrowser.ExecWB(6,1) type=button value=打印> 
   6. <input name=Button onClick=document.all.WebBrowser.ExecWB(6,6) type=button value=直接打印> 
   7. <input name=Button onClick=document.all.WebBrowser.ExecWB(7,1) type=button value=打印预览> 
   8. <input name=Button onClick=document.all.WebBrowser.ExecWB(8,1) type=button value=页面设置> 
   9. <input name=Button onClick=document.all.WebBrowser.ExecWB(10,1) type=button value=属性> 
10. <input name=Button onClick=document.all.WebBrowser.ExecWB(17,1) type=button value=全选> 
11. <input name=Button onClick=document.all.WebBrowser.ExecWB(22,1) type=button value=刷新> 
12. <input name=Button onClick=document.all.WebBrowser.ExecWB(45,1) type=button value=关闭> 
<OBJECT classid=CLSID:8856F961-340A-11D0-A96B-00C04FD705A2 height=0 id=WebBrowser width=0></OBJECT> 
<input name=Button onClick=document.all.WebBrowser.ExecWB(1,1) type=button value=打开>
<input name=Button onClick=document.all.WebBrowser.ExecWB(2,1) type=button value=关闭所有>
<input name=Button onClick=document.all.WebBrowser.ExecWB(4,1) type=button value=另存为> 
<input name=Button onClick=document.all.WebBrowser.ExecWB(6,1) type=button value=打印>
<input name=Button onClick=document.all.WebBrowser.ExecWB(6,6) type=button value=直接打印>
<input name=Button onClick=document.all.WebBrowser.ExecWB(7,1) type=button value=打印预览>
<input name=Button onClick=document.all.WebBrowser.ExecWB(8,1) type=button value=页面设置>
<input name=Button onClick=document.all.WebBrowser.ExecWB(10,1) type=button value=属性>
<input name=Button onClick=document.all.WebBrowser.ExecWB(17,1) type=button value=全选>
<input name=Button onClick=document.all.WebBrowser.ExecWB(22,1) type=button value=刷新>
<input name=Button onClick=document.all.WebBrowser.ExecWB(45,1) type=button value=关闭>
三.使用ScriptX.cab控件
1.下载ScriptX.cab控件
官网http://www.meadroid.com/scriptx/index.asp
2.使用object元素,修改codebase,classid的值
这里调用控件ScriptX.cab
Java代码 复制代码
   1. <OBJECT id="factory" style="DISPLAY: none" codeBase="${rootUrl}js/smsx.cab#VVersion=6,3,435,20" classid="clsid:1663ed61-23eb-11d2-b92f-008048fdd814" viewastext></OBJECT> 
<OBJECT id="factory" style="DISPLAY: none" codeBase="${rootUrl}js/smsx.cab#VVersion=6,3,435,20" classid="clsid:1663ed61-23eb-11d2-b92f-008048fdd814" viewastext></OBJECT>
这段代码用来加载cab文件,clsid和codebase必须要和你下载的cab中的信息对应,否则组件会加载错误,这两项其实不难找,只要你用winrar打开你下载的cab文件,然后找到扩展名是.inf的文件,然后打开之,就能看到了。
3.调用控件脚本
Print.js文件
Java代码 复制代码
   1. function setPrintBase(headerText,footerText,rootUrl) { 
   2.   
   3.     // -- advanced features ,未曾使用过,有待确认。 
   4.   
   5.         //factory.printing.SetMarginMeasure(2); // measure margins in inches 
   6.   
   7.         //factory.SetPageRange(false, 1, 3);// need pages from 1 to 3 
   8.   
   9.         //factory.printing.printer = "HP DeskJet 870C"; 
10.   
11.         //factory.printing.copies = 2; 
12.   
13.         //factory.printing.collate = true; 
14.   
15.         //factory.printing.paperSize = "A4"; 
16.   
17.         //factory.printing.paperSource = "Manual feed" 
18.   
19.     var header = (headerText==null||headerText=="")?'默认页眉':headerText; 
20.   
21.     var footer = (footerText==null||footerText=="")?'默认页角':footerText; 
22.   
23.   factory.printing.header = "&b"+header+"&b" ; 
24.   
25.   factory.printing.footer = "&b"+footer; 
26.   
27.   factory.printing.portrait = true; 
28.   
29.   factory.printing.leftMargin =10.00; 
30.   
31.   factory.printing.topMargin =10.00; 
32.   
33.   factory.printing.rightMargin =10.00; 
34.   
35.   factory.printing.bottomMargin =10.00; 
36.   
37. } 
function setPrintBase(headerText,footerText,rootUrl) {
    // -- advanced features ,未曾使用过,有待确认。
        //factory.printing.SetMarginMeasure(2); // measure margins in inches
        //factory.SetPageRange(false, 1, 3);// need pages from 1 to 3
        //factory.printing.printer = "HP DeskJet 870C";
        //factory.printing.copies = 2;
        //factory.printing.collate = true;
        //factory.printing.paperSize = "A4";
        //factory.printing.paperSource = "Manual feed"
    var header = (headerText==null||headerText=="")?'默认页眉':headerText;
    var footer = (footerText==null||footerText=="")?'默认页角':footerText;
factory.printing.header = "&b"+header+"&b" ;
factory.printing.footer = "&b"+footer;
factory.printing.portrait = true;
factory.printing.leftMargin =10.00;
factory.printing.topMargin =10.00;
factory.printing.rightMargin =10.00;
factory.printing.bottomMargin =10.00;
}

四.对比
1.Window.print调用方便,但功能简单
2.功能更强大,但使用IEWebBrowser有时会报JS没有权限的错误。
3.ScriptX控件功能也比较强大,目前在使用这种方式。
这里的也不错啊,有打印到 word的和excel

㈣ 使用Javascript怎样自动打印页面
1、js实现(可实现局部打印)
[html] view plain 
<input id="btnPrint" type="button" value="打印" onclick="javascript:window.print();" />
<input id="btnPrint" type="button" value="打印预览" onclick=preview(1) />
<style type="text/css" media=print>
.noprint{display : none }
</style>
<p class="noprint">不需要打印的地方</p>
<script>
function preview(oper)
{
if (oper < 10)
{
bdhtml=window.document.body.innerHTML;//获取当前页的html代码
sprnstr="<!--startprint"+oper+"-->";//设置打印开始区域
eprnstr="<!--endprint"+oper+"-->";//设置打印结束区域
prnhtml=bdhtml.substring(bdhtml.indexOf(sprnstr)+18); //从开始代码向后取html
prnhtml=prnhtml.substring(0,prnhtml.indexOf(eprnstr));//从结束代码向前取html
window.document.body.innerHTML=prnhtml;
window.print();
window.document.body.innerHTML=bdhtml;
} else {
window.print();
}
}
</script>
<p>XXXXX</p>
<!--startprint1-->要打印的内容<!--endprint1-->
再加个打印按纽 onclick=preview(1)   
2、调用windows底层打印,报安全警告,不建议使用(不支持局部打印)
[html] view plain 
<HTML>
<HEAD>
<TITLE>javascript打印-打印页面设置-打印预览代码</TITLE>
<META http-equiv=Content-Type content="text/html; charset=gb2312" />
<SCRIPT language=javascript>
function printsetup(){
// 打印页面设置
wb.execwb(8,1);
}
function printpreview(){
// 打印页面预览
wb.execwb(7,1);
}
function printit()
{
if (confirm('确定打印吗?')) {
wb.execwb(6,6);
}
}
</SCRIPT>
</HEAD>
<BODY>
<DIV align=center>
<OBJECT id=wb height=0 width=0
classid=CLSID:8856F961-340A-11D0-A96B-00C04FD705A2 name=wb></OBJECT>
<INPUT onclick=javascript:printit() type=button value=打印 name=button_print />
<INPUT onclick=javascript:printsetup(); type=button value=打印页面设置 name=button_setup />
<INPUT onclick=javascript:printpreview(); type=button value=打印预览 name=button_show />
一按开始的减肥了卡时间段
</DIV>
</BODY>
</HTML>   
3、jQuery实现(支持局部打印)
[html] view plain 
<script type="text/javascript" src="jquery-1.4.2.min.js"></script>
<script type="text/javascript" src="jquery.PrintArea.js"></script>
<script>
$(document).ready(function(){
$("input#biuuu_button").click(function(){
$("div#myPrintArea").printArea();
});
});
</script>
<input id="biuuu_button" type="button" value="打印"></input>
<div id="myPrintArea">.....文本打印部分.....</div>
㈤ jS使字符串不换行显示!很急在线等!!!!!!!!!!!!!!!!!!!!!!!!!
用js查找试试看字符串里是否含有“\n”?若是有,可以把\n替换为空字符试试看
