When assigning a value to the text box through js code, FireFox’s innerHTML cannot get the value of the text box.
If you modify the source code slightly, f556995bf475049fc7b1265f3f2451ec
Write the value in the text box in advance, and then modify it to CCCC through js. It displays as CCCC in IE, but displays as AAAA in FF, which means that the text cannot be obtained in Firefox. The value written dynamically in the box.
Conclusion: FireFox is really not an ordinary waste.
This is indeed the case, and the same is true in Chrome and Opera.
Since the internal structure of HTML that requires this function is very complex, it is too complicated to traverse the value and assign it back. Finally, my processing result is
if(ISFF)
{
alert("Due to FireFox function defect, this operation does not support calling under FireFox, please use IE browser instead.");
return;
}
I just encountered a problem, that is, XML cannot be used in Firefox Next, if the length of the node content value exceeds 4096, it will be automatically cut into multiple nodes. I was confused and struggled for a long time before I made the processing code.
The standard is useless. Many functions are either not supported or have bugs. It's annoying that the code must support both IE and FireFox, and then FireFox, all at the same time.
Sometimes, if you want to be compatible with all browsers, you have to first judge with js, and then call different methods!
I would be very happy if I could do this, but the key is that it doesn’t work.
There are many places to make judgments in the code
if(isie)
… document.getElementById("inp1").setAttribute("value","ccc");
This is just an example to illustrate this problem. The real program is very complicated. The values in the text box are all filled in manually
You can learn from the source code of jquery to see how it gets the value
The same goes for jq. It felt like this was a browser issue, so I checked. =. =!
ff chrome opera ie9 is like this. . .
No, IE9 is like this too?!
IE9 doesn’t have this problem, I tried it
Don’t scare me, this is a very important feature.
Don’t scare me, this is very important Function.
IE9 is 100% the same. You can use IE9 to test on your test page. I am using x64 IE document mode IE9 browser mode IE9
document.getElementById("inp1").addEventListener("keyup",function(){document.getElementById("inp1").setAttribute("value",document.getElementById("inp1").value);},false);You may be using Quirks mode.
smsType = document.getElementById("smsType").value;
calledNumber = document.getElementById("calledNumber").value;
content = document.getElementById("content" ).value;
content = encodeURIComponent(content);
Clear the history of ff to update!
