html编辑文本固定分页,富文本编辑器[WYSIWYG],使用javascript进行分页

是否可以使用JavaScript在富文本编辑器中实现类似于MS Word的分页.

我需要使用包含页面文本的JavaScript来实现编辑器.如果我输入的文本超出了页面的限制,则将自动创建一个新页面,并且文本将以完整的格式溢出到新页面.另外,如果我从其他来源复制大文本,则它应根据文本长度计算页面数,并将其划分为具有原始文本所有格式的页面.

我需要仅使用JavaScript,HTML和CSS根据像素大小将文本分成几行.

如果我从页面内部删除内容,则应该在当前页面中填充下一页的内容,如果删除页面中的所有内容,则应该删除该页面. MS word中几乎所有的寻呼功能都应在此实现.

解决方法:

请尝试这个…

Javascript代码pagination.js文件

function Pager(tableName, itemsPerPage) {

this.tableName = tableName;

this.itemsPerPage = itemsPerPage;

this.currentPage = 1;

this.pages = 0;

this.inited = false;

this.showRecords = function(from, to) {

var rows = document.getElementById(tableName).rows;

// i starts from 1 to skip table header row

for (var i = 1; i < rows.length; i++) {

if (i < from || i > to)

rows[i].style.display = 'none';

else

rows[i].style.display = '';

}

}

this.showPage = function(pageNumber) {

if (! this.inited) {

alert("not inited");

return;

}

var oldPageAnchor = document.getElementById('pg'+this.currentPage);

oldPageAnchor.className = 'pg-normal';

this.currentPage = pageNumber;

var newPageAnchor = document.getElementById('pg'+this.currentPage);

newPageAnchor.className = 'pg-selected';

var from = (pageNumber - 1) * itemsPerPage + 1;

var to = from + itemsPerPage - 1;

this.showRecords(from, to);

}

this.prev = function() {

if (this.currentPage > 1)

this.showPage(this.currentPage - 1);

}

this.next = function() {

if (this.currentPage < this.pages) {

this.showPage(this.currentPage + 1);

}

}

this.init = function() {

var rows = document.getElementById(tableName).rows;

var records = (rows.length - 1);

this.pages = Math.ceil(records / itemsPerPage);

this.inited = true;

}

this.showPageNav = function(pagerName, positionId) {

if (! this.inited) {

alert("not inited");

return;

}

var element = document.getElementById(positionId);

var pagerHtml = ' « Prev | ';

for (var page = 1; page <= this.pages; page++)

pagerHtml += '' + page + ' | ';

pagerHtml += ' Next »';

element.innerHTML = pagerHtml;

}

}
