我们有一个定制的CRM，可以将IMG保存在我们的数据库中，/upload/image/image.jpg但是我们也有带有完整URL的图像。我需要一种方法来找出图像是否以/ upload开头并将我们的网址添加到该图像src的前面，以便该图像正确显示并且不会出现没有图像的正方形，
我们正在使用JSON和javascript，这是到目前为止的代码
function loadnewsstory(e)
{
if(newsview !== true)
{
document.getElementById("newsarticals").style.display = "block";
document.getElementById("activecontent").style.display = "none";
newsview = true;
}
xmlhttp=new XMLHttpRequest();
xmlhttp.open("POST","http://media.queerdio.com/mobileDevice/?uri=loadstory/"+e ,false);
xmlhttp.send();
var newsreponse = JSON.parse(xmlhttp.responseText);
var news = newsreponse[0];
document.getElementById("newsarticals").innerHTML = '<h1 class="newsheader">' + news.post_title + '</h1> <div class="newsbody">'+news.post_content+'</div>';
window.scrollTo(0,0);
}
我们需要看的部分是news.post_content。
编辑：添加了JSON看起来像
"post_content":"<p>DR SHARON Giese is a household name in America, starring on hit medical shows Dr Oz and The Doctors and making regular appearances on CBS News, CNN and NBC.<\/p>\n<p>Dr Giese is ranked among the best in her field but, as one family discovered \"with tragic consequences\" even the best make mistakes.<\/p>\n<center><img src=\"..\/..\/..\/upload\/Health\/Dr Sharon Giese - Dr OZ - YouTube.jpg\" alt=\"Dr Oz Show - DR SHARON\" width=\"650\" height=\"488\" \/><\/center>\n<div style=\"padding: 0; margin: -6px 0 4px 10px; text-align: left;\">A screen grab from a recent appearance on the Dr Oz show. Picture: YouTube Source: YouTube<\/div>\n<p>In June 2009, 32-year-old mother-of-two Adriana Porras underwent liposuction, a fat reduction procedure performed by Dr Giese. Ms Porras died two days later of a pulmonary embolism.<\/p>\n<p>Her husband Pablos Balzola then sued Dr Giese for negligence, claiming she did not return their frantic calls when Ms Porras showed signs of severe post-surgery complications, complaining of chest pains and shortness of breath.<\/p>\n<p>In court, pathologists testified that had she received treatment for those symptoms, her chance of survival would have been much higher.<\/p>\n<p>It was later found out that Dr Giese had not performed the procedure in a hospital but in her own home office.<\/p>\n<p>This week she finally reached a settlement with Mr Balzola, agreeing to pay US$2.3 million (AUD$2.5 million)<\/p>\n<p>The money will reportedly be split between the widower, his six-year-old daughter Maia and nine-year-old son Nicholas. Mr Balzola"
我已将此代码用于我们的feature_images
if(news.featured_image.substring(0, 7) !== "http://")
{
news.featured_image = "http://www.radiobreakout.com.au/"+news.featured_image;
}
但是如何获取post_content中的img srcs。
请考虑以下几点：
var articles = document.getElementById('newsarticals');
var activeContent = document.getElementById('activecontent');
var httpUrl = /^http:/;
function loadnewsstory(e) {
if (newsview !== true) {
articles.style.display = 'block';
activeContent.style.display = 'none';
newsview = true;
}
var xmlhttp = new XMLHttpRequest();
xmlhttp.open('POST','http://media.queerdio.com/mobileDevice/?uri=loadstory/' + e , false);
xmlhttp.send();
// empty the articles element first
while (articles.children.length) articles.removeChild(articles.firstChild);
// create a document fragment out of the response
var newsArray = JSON.parse(xmlhttp.responseText);
var newsEl = newsArray.reduce(function htmlCreator(frag, news) {
// create the elements properly first
var header = document.createElement('h1');
var div = document.createElement('div');
header.className = 'newsheader';
header.appendChild(document.createTextNode(news.post_title));
// innerHTML shouldn't really be used, but we'll let it slide this time
// next time don't store html in json
div.innerHTML = news.post_content;
div.className = 'newsbody';
// loop through all of the newly added images to change the sources
Array.prototype.forEach.call(div.querySelectorAll('img'), function sourceMangler(el) {
if (!httpUrl.test(el.src)) el.src = 'http://www.radiobreakout.com.au/' + el.src.split('/').filter(function removeSome(part) { return (part && part !== '..'); }).join('/');
});
frag.appendChild(header);
frag.appendChild(div);
return frag;
}, document.createDocumentFragment());
// append the fragment to the empty element
articles.appendChild(newsEl);
window.scrollTo(0,0);
}
