Question

我有一个字符串

var string = "mario rossi laureato";

我只有15个字符可用于写入表格。

所以预期的结果应该是这样的：

<td id="firstTD">mario rossi</td> //this td has 15 characters available
<td id="secondTD">laureato</td>

第十五位与“laureato”这个词相交，所以它计算了多余的，并取了前一个词。

另一个例子：

var string2 = "hello my name is Paolo"

所以预期的结果应该是这样的：

<td id="firstTD">hello my name</td> //this td has 15 characters available
<td id="secondTD">is Paolo</td>

第十五位与单词“is”相交，所以它计算了多余的，并取了前一个单词。

伙计们对此有何想法？

Answer 1

你可以这样做：

var str = "mario rossi laureato";
var strArr = str.match(/.{1,15}/g);
console.log(strArr.length);
for(var s=0,slen=strArr.length; s < slen; s++) {
    console.log(strArr[s]);
    //create td and append or append strArr[s] to existing td
}

Answer 2

试试这个：http://jsfiddle.net/Zh8RR/

// Sample string, to make it easy to see the cut points I've use 1-15 in hex to give us a nice easy way to see the breaks
var string = "1234567 9ABCDE 12345 7 89AB 123456 89ABC E 12 45 789A CD 123";

// Break input string up into words
var parts = string.split(' ');
var sections = [""];
var rows = 0;
// For each word
for (var i = 0; i < parts.length; ++i) {
    // If it makes the section too long push it to the next section:
    if (sections[rows].length + parts[i].length + 1 > 15) {
        rows++;
    }
    // If we have no text initialise it to be the current word
    if(!sections[rows]) {
        sections[rows] = parts[i];
    } else {
        // Otherwise use a space as a separator and concat them.
        sections[rows] += " " + parts[i];
    }
}
// Write them out to a sample div so we can check.
$('div').html(sections.join("<br />"));

在td中拆分可能具有最大字符数的字符串
