我想在<tag>
和</tag>
内插入中文字符和数字(或字母)之间的空格。
EX1:
原始字符串:
<a href="http://example.com/漢字1234.html">it's a Chinese character漢字1234</a>
预期结果:
<a href="http://example.com/漢字1234.html">it's a Chinese character 漢字 12345</a>
EX2:
更复杂的原始字符串:
<div id="foo">
<div class="bar1">
<span>abcd漢字1234</span>
</div>
<div class="bar2">
123漢字abcd
<p>letters漢字<a href="http://example.com/漢字1234.html">42漢字answer</a></p>
</div>
</div>
预期结果:
<div id="foo">
<div class="bar1">
<span>abcd 漢字 1234</span>
</div>
<div class="bar2">
123 漢字 abcd
<p>letters 漢字<a href="http://example.com/漢字1234.html">answer 漢字 42</a></p>
</div>
</div>
这是我在JavaScipt中所做的:
function insert_space(text) {
// I use [\u4E00-\u9FA5] to match Chinese characte
text = text.replace(/([\u4E00-\u9FA5])([a-z0-9])/ig, '$1 $2');
text = text.replace(/([a-z0-9])([\u4E00-\u9FA5])/ig, '$1 $2');
return text;
}
function replaceEntry() {
var target_tags = ['div', 'p', 'li', 'td', 'span', 'a', 'h1', 'h2', 'h3', 'h4', 'h5', 'h6'];
var body_tag = $('body');
var raw_text;
var format_text;
for (var i = 0; i < target_tags.length; i++) {
var target_tag = target_tags[i];
$(target_tag, body_tag).each(function() {
var has_children = false;
console.log('\n');
console.log(target_tag + ' begin');
raw_text = $(this).html();
console.log(raw_text);
format_text = insert_space(raw_text);
$(this).html(format_text);
console.log(target_tag + ' end');
console.log('\n');
});
}
}
replaceEntry();
但是这段代码无法处理上面的那两个例子。
我需要一个忙。非常感谢。
PS。
我将此代码放入Google Chrome扩展程序中,例如:
chrome.browserAction.onClicked.addListener(function(tab) {
chrome.tabs.executeScript(tab.id, {file: 'js/libs/jquery-1.7.1.min.js'});
chrome.tabs.executeScript(tab.id, {file: 'js/auto_spacing.js'});
});
的更新:
我找到了一个解决方案:使用XML XPath
var current_documant = window.document;
var xpath_query = '//text()[normalize-space(.)][translate(name(..),"ABCDEFGHIJKLMNOPQRSTUVWXYZ","abcdefghijklmnopqrstuvwxyz")!="script"][translate(name(..),"ABCDEFGHIJKLMNOPQRSTUVWXYZ","abcdefghijklmnopqrstuvwxyz")!="style"]';
var nodes = current_documant.evaluate(xpath_query, current_documant, null, XPathResult.UNORDERED_NODE_SNAPSHOT_TYPE, null);
var nodes_length = nodes.snapshotLength;
for (var i = 0; i < nodes_length; ++i) {
var current_node = nodes.snapshotItem(i);
// http://www.w3school.com.cn/xmldom/dom_text.asp
current_node.data = insert_space(current_node.data);
}
答案 0 :(得分:1)
function doReplace( str ) {
var rchinese = /([\u4E00-\u9FA5]+)/g;
var root = document.createElement("div");
root.innerHTML = str;
['div', 'p', 'li', 'td', 'span', 'a', 'h1', 'h2', 'h3', 'h4', 'h5', 'h6'].forEach( function( tagName ) {
[].forEach.call( root.getElementsByTagName( tagName ), function( elem ) {
[].forEach.call( elem.childNodes, function( node ) {
if( node.nodeType === 3 ) {
node.nodeValue = node.nodeValue.replace( rchinese, " $1 ");
}
});
});
});
return root.innerHTML;
}
结果:
var test = '<a href="http://example.com/漢字1234.html">it\'s a Chinese character漢字1234</a>';
doReplace(test);
//<a href="http://example.com/漢字1234.html">it's a Chinese character 漢字 1234</a>
