调用浏览器的打印预览

JS 实现浏览器打印、打印预览
目前正在做浏览器端采用JS方式实现打印这么一个功能,JS打印实现的方法很多,但是兼容各个浏览器实现打印预览的功能有些棘手,现将实现的内容及遇到的问题记录下来,希望有大牛看到所提的问题后可以给予解答,在此感谢啦。 1.JS实现打印的方式 方式一:window.print() window.print();会弹出打印对话框,打印的是window.document.body.innerHTML中的
IE浏览器实现打印预览
最近遇到这么一个需求,需要在IE浏览器上打印的时候,不直接调用打印机,而是先打开打印预览页面,再进行打印操作。这样,就需要对原本的打印方法进行改写了。具体实现如下:在jsp页面进行以下操作。<!-- 在body标签中写入一个object --> <object id="printWB" style="dispaly:none" classid="clsid:8856F961-340A-11D0-A9
JavaScript实现打印和打印预览功能
1、打印:First Method: Window.Print();打印预览:First Method: 先制作一张跟打印效果一样的页,在该页显示后调用Window.Print();2、function start(v){try{printWB.ExecWB(v,1);}catch(e){}window.close();}使用方法:obiect是打印的控件,要放在 前。start是打印的函数,v是
