本文实例讲述了javascript弹出带文字信息的提示框效果。分享给大家供大家参考，具体如下：
tooltips.js:
// position of the tooltip relative to the mouse in pixel //var offsetx = 12;var offsety = 8;function newelement(newid){ if(document.createElement) { var el = document.createElement('div'); el.id = newid; with(el.style) { display = 'none'; position = 'absolute'; } el.innerHTML = ''; document.body.appendChild(el); }}var ie5 = (document.getElementByIdx && document.all);var ns6 = (document.getElementByIdx && !document.all);var ua = navigator.userAgent.toLowerCase();var isapple = (ua.indexOf('applewebkit') != -1 ? 1 : 0);function getmouseposition(e){ if(document.getElementByIdx) { var iebody=(document.compatMode && document.compatMode != 'BackCompat') ? document.documentElement : document.body; pagex = (isapple == 1 ? 0:(ie5)?iebody.scrollLeft:window.pageXOffset); pagey = (isapple == 1 ? 0:(ie5)?iebody.scrollTop:window.pageYOffset); mousex = (ie5)?event.x:(ns6)?clientX = e.clientX:false; mousey = (ie5)?event.y:(ns6)?clientY = e.clientY:false; var lixlpixel_tooltip = document.getElementByIdx('tooltip'); lixlpixel_tooltip.style.left =(mousex+pagex+offsetx) + 'px'; lixlpixel_tooltip.style.top =(mousey+pagey+offsety) + 'px'; }}function tooltip(tip){ if(!document.getElementByIdx('tooltip')) newelement('tooltip'); var lixlpixel_tooltip = document.getElementByIdx('tooltip'); lixlpixel_tooltip.innerHTML = tip; lixlpixel_tooltip.style.display = 'block'; document.onmousemove = getmouseposition;}function exit(){ document.getElementByIdx('tooltip').style.display = 'none';}test.html
