Javascript：如何获取p标签内的文本字符串数组

Question

Lets say I have string with a lot of p tags in it...

var myString = "<p>Some text.</p><p>Some more. Some more text.</p><p>And even some more text.</p>";

..how do I get an array, each item in the array is a string of text that was in the p tags:

 [
    "Some text.",
    "Some more. Some more text.",
    "And even some more text."
]

One way I suppose would be to get rid of the p tags...

   var stringWithOutTags = myString.replace(/(<p>|<\/p>)/g, " ");

..And then use .split() to get out each sentence. But I don't really want to get out each sentence, just text w.in p tags

var stringAsArray = stringWithOutTags.split(".");

Answer 1

If you are executing the code on browser, you can parse the string as HTML instead of using regular expression:

var el = document.createElement('div');
el.innerHTML = myString;
var texts = [].map.call(el.querySelectorAll('p'), function(p) {
   return p.textContent;
});

Answer 2

您可以从字符串中省略<p>标记，而仅使用结束</ p>标记进行拆分，以获得所需的结果。

myString.replace('<p>', '').split('</p>');

Answer 3

Note: please only use this method if you are sure that you can trust the input string (ie it is not user input)!

var myString = "<p>Some text.</p><p>Some more. Some more text.</p><p>And even some more text.</p>";

// Create a "div" element
var div = document.createElement("div");

// Get browser to parse string, and set the parsed HTML elements as
// the contents of the div element
div.innerHTML = myString;

// Loop over the child elements of the div, and return an array of
// the textual content the elements. If you wish to preserve tags
// inside the <p> elements, replace .textContent with .innerHTML
var arrayOfStrings = Array.prototype.map.call(div.childNodes, function (pTag) {
    return pTag.textContent;
});

Why not split after you replace:

var a = "<p>Some text.</p><p>Some more. Some more text.</p><p>And even some more text.</p>";

var b = a.replace(/(<p>|<\/p>)/g, " ").split('  ');
