Javascript/CSS调整div同步大小



我在一个网站上有一些代码,它重新调整了网页中几个水平对齐的div的大小,但它们同时重新调整了大小,导致div被替换,网页看起来很难看。如何让javascript代码等到收缩完div后再扩展另一个div?

CSS:

#左侧面板、#中间面板、#右侧面板{过渡:宽度2s;-moz转换:宽度2s;/*Firefox 4*/-webkit转换:宽度2s;/*Safari和Chrome*/-o-transition:宽度2s;/*Opera*/}

Javascript:

函数大小按钮(div){if(div=='leftpanel'){#这段代码缩小了其他div,它应该首先运行,而不放大任何其他divdocument.getElementById('middlepanel').style.width='20%';document.getElementById('rightpanel').style.width='20%';}if(div=="middlepanel"){document.getElementById('leftpanel').style.width='20%';document.getElementById('rightpanel').style.width='20%';}if(div=='rightpanel'){document.getElementById('leftpanel').style.width='20%';document.getElementById('middlepanel').style.width='20%';}#该代码应该在其他div收缩后第二次运行,现在它在其他div缩小的同时放大document.getElementById(div).style.width='50%';}

听起来回调函数可能会起作用?

类似于:

function resizebutton(div)
{
    if (div == 'leftpanel'){
        #this code shrinks the other divs, it should run first, without any other divs being enlarged
        document.getElementById('middlepanel').style.width = '20%';
        document.getElementById('rightpanel').style.width = '20%';
    }
    if (div == 'middlepanel'){
        document.getElementById('leftpanel').style.width = '20%';
        document.getElementById('rightpanel').style.width = '20%';
    }
    if (div == 'rightpanel'){
        document.getElementById('leftpanel').style.width = '20%';
        document.getElementById('middlepanel').style.width = '20%';
    }

}
function resizeMeFirst(div, callback) {
    document.getElementById(div).style.width = '50%';
    //ok, now that that is done, run the callback function.
    callback(div)    
}
resizeMeFirst(div, resizebutton);
