使用Javascript / jQuery将HTML分成多列 [英] Splitting HTML into multiple columns with Javascript/jQuery

问题描述

注意：这是针对此问题的另一种计划方法： Joomla中的多栏文章

Note: This is an alternate planned approach to this question: Multiple column articles in Joomla

我有一个客户需要多列布局，应该从非列HTML块自动生成。

I've got a client who wants a multi column layout, which should be generated automatically from a non-column HTML block.

使用JavaScript（和jQuery）从单个HTML块创建多列系统的可行性如何？如果可能的话我该怎么做呢？

What is the feasibility of using JavaScript (and jQuery) to create a multi-column system from a single block of HTML? And if it is possible how would I go about doing it?

谢谢。

Thanks.

推荐答案

这只是一个例子，你可以如何解决你的问题。

This is just an example how you can solve your problem. Of cause this solution can be refined.

function textSplitter(){
}

textSplitter.prototype.LENGTH_TO_SPLIT=5000 //max chars in single line

textSplitter.prototype.split=function(id){
    var contentDiv=document.getElementById(id); // get an element
    var text=contentDiv.innerHTML; 
    var length= text.length; 
    if(length){
        var div1sbstr=text.substring(0,this.LENGTH_TO_SPLIT); //take a substring
        var div1=document.createElement("div");
        contentDiv.appendChild(div1); // append it
    }
    if(length>this.LENGTH_TO_SPLIT){
        var div2sbstr=text.substring(this.LENGTH_TO_SPLIT,this.LENGTH_TO_SPLIT*2);
        var div2=document.createElement("div");
        contentDiv.appendChild(div2);
    }
    if(length>this.LENGTH_TO_SPLIT*2){
        var div3sbstr=text.substring(this.LENGTH_TO_SPLIT*2,this.LENGTH_TO_SPLIT*3);
        var div3=document.createElement("div");
        contentDiv.appendChild(div3);
    }
}
