If the text We are sorry but we made a boo boo
appears then
I would like to do this in JavaScript.
Here is an attempt
(function () {
"use strict";
function walkTheDOM(node, func) {
if (node && node.nodeType) {
if (typeof func === "function") {
func(node);
}
node = node.firstChild;
while (node) {
walkTheDOM(node, func);
node = node.nextSibling;
}
}
}
function filterElementsByContains(elements, string) {
var toStringFN = {}.toString,
text = toStringFN.call(elements),
result,
length,
i,
element;
if (text !== "[object NodeList]" && text !== "[object Array]" && !($() instanceof jQuery)) {
return result;
}
result = [];
if (typeof string === "string") {
string = new RegExp("^" + string + "$");
} else if (toStringFN.call(string) !== "[object RegExp]") {
return result;
}
function getText(node) {
if (node.nodeType === 3) {
text += node.nodeValue;
}
}
length = elements.length;
i = 0;
while (i < length) {
text = "";
element = elements[i];
walkTheDOM(element, getText);
if (string.test(text)) {
result.push(element);
}
i += 1;
}
return result;
}
if(filterElementsByContains([document.getElementsByTagName("table")[0]], /We are sorry but we made a boo boo/).length) {
location.reload();
}
The above could should, I think, work for the text if it appears in a specific place. I want to make it more general - so that the text could appear anywhere on that page.
Also, I would like to know how to add a pause so that, for example, it waits 5 seconds before reloading.
I guess I would add incorporate something like:
setTimeout(
function()
{
//location.reload();
}, 5000);
Just do an indexOf on the body's textContent / innerText property
var content = document.body.textContent || document.body.innerText;
var hasText = content.indexOf("We are sorry but we made a boo boo")!==-1;
if(hasText){
setTimeout(function(){
window.location = "http://www.example.com";
},5000);
}
This may work:
var bodyText = document.body.textContent || document.body.innerText;
var msg = "We are sorry but we made a boo boo";
if (bodyText.indexOf(msg) > -1) {
setTimeout(function() {
location.reload();
}, 5000);
}
--sorry for nearly duplicate answer :\\ --
--edit--
Tell me - how can I add a second rule, it's a different way of phrasing the error message: There was an internal error in our system. We logged the problem and will investigate it later.
This will check for both messages:
var bodyText = document.body.textContent || document.body.innerText;
var msg = [
"We are sorry but we made a boo boo",
"There was an internal error in our system. We logged the problem and will investigate it later."
];
var flag = false;
for (var i = 0; i < msg.length; i++) {
if bodyText.indexOf(msg[i]) {
flag = true;
}
}
if (flag) {
setTimeout(function() {
location.reload();
}, 5000);
}
Explanation: All I did was modify msg
to be an array of strings rather than a string itself. Then for every msg
we want to check, we loop through the values and compare msg
against bodyText
. If bodyText
contains one of the msg
's, we set a flag
to true
, and then perform an if statement on flag
.
