[英]replace tags in javascript regexp
I am doing an REGEXP tool, that accepts input in text and showing the results in a div. 我正在做一个REGEXP工具,该工具接受文本输入并在div中显示结果。 I replace the matches with a <b>Match</b> when show results.
显示结果时,我用<b>匹配</ b>替换匹配项。 If it matches raw text it works fine but the problem is when insert HTML code
如果它与原始文本匹配,则可以正常工作,但问题是在插入HTML代码时
I want to replace all tags except <b> tag with html entities, how can achieved that? 我想用HTML实体替换除<b>标记之外的所有标记,如何实现?
var regExpTool = {
makeRegexp: function(pattern, opts){
var regexp = new RegExp(pattern, opts);
return regexp;
},
createResults: function(pattern, string, opts){
var res = string.replace(this.makeRegexp(pattern, opts), "<b>$&</b>")
results.style.display = "block";
text.style.display = "none";
results.innerHTML = res;
}
}
Perhaps your code should look more like: 也许您的代码应该更像:
var win = window, doc = document, bod = doc.getElementsByTagName('body')[0];
function E(e){
return doc.getElementById(e);
}
function regExpTool(text, outputElement){
this.makeBold = function(options){
outputElement.innerHTML = text.replace(new RegExp('^(<.+>)*('+text+')(<\/.+>)*$', options), '<b>$2</b>')
outputElement.style.display = 'block';
};
}
new regExpTool('<div>now</div>', E('wow')).makeBold();
Note, that there is no reason for your makeRegexp
method. 请注意,没有
makeRegexp
方法。

It won't work with self closing tags. 它不能与自闭标签一起使用。
