For help, a.h HTML on how the json data is passed to the b.h HTML page?-CodePudding

A.h HTML code is as follows: click on the button to adjust to the b.h HTML page, and then passed the json

 
<script> 
{$. Alarmctrl=function (ctrldata) 
The console. The log (ctrldata); 
Var url="b.h HTML? Ctrldata="HTTP://https://bbs.csdn.net/topics/+encodeURI (ctrldata); 
The location. The href=https://bbs.csdn.net/topics/url; 
} 
</script>

B.h HTML code is as follows:

 
<script> 
//receive the json array 
Var param=decodeURI (location. Search); 
If (param!=null & & Param! {
="")Param=param. Substring (param. IndexOf ("=") + 1, param. Length); 
Alert (param); 
Alert (JSON. Stringify (param)); 
} 
</script>

You're just

For help, b.h HTML how to obtain the json data, thank you! The above code is not an error, but the result is wrong,

Do you want to transfer an object to b.h HTML ctrldata parameters on duty, but is an object, you send encodeURI method can not get the results you want, you can either use JSON. The first stringifyl into a string, get url parameter and then JSON. Parse back

Or don't attached to the directly? ctrldata=https://bbs.csdn.net/topics/behind the duty, direct:

 Object. Keys (ctrldata). The map (key=& gt; Key + '=' + ctrldata [key]). Join (' & amp; ')

,
Generate
B.h HTML? ServerPort1=10202 & amp; ServerPort2=10203 & amp; CtrlType=3 & amp; ServerIP=192.168.1.18 & amp; CtrlID=105
So the conventional url good

Then you're b.h went to read in the TML ServerPort1, ServerPort2
