dataAcquisition.js is a collect what happens to the user on the web page behavior and abnormal data usage

Everyone has any needs or dissatisfaction in the use process
You can give me pull requests
If it helps you, please give me a star

1. Realize front-end data reporting and analysis
2. Realize user data portrait modeling and behavior trace analysis
3. Realize active burying point and automatic burying point reporting
4. Achieve front-end page loading speed reporting
5. Implement front-end interface exception reporting
6. Implementation of front-end code exception reporting

1. Clone code to local
2. Modify store.sendurl to submit interface address
3. Modify the store.selector input element selector to specify the input event listening range
4. If you want to filter the input collection, you can change store.acrange to specify, and password is better not to collect. Here is an example only
5. Click the element to bubble up and collect two layers by default. You can modify store.acblength to change the number of layers
6. Place file before logical code load (AMD supported)
7. The server directory is the collection data receiver developed based on node.js

Only need to modify the classTag configuration to realize the two collection methods.
Collect all elements when classTag is empty
When a classTag has a value, only the elements in the class containing the value are collected

Just call window.dataAc.postData()

sendUrl      : "http://localhost:9090/logStash/push",   //Collection data receiving address     
selector     : 'input',     //Configure the selector of input box to limit the listening range of input, focus and blur events;      
acRange      : ['text','tel'],   //Configure the type attribute of the input box to control the collection range     
maxDays      : 5,           //Cookie duration, default: 5 days      
userSha      : 'userSha',   //User uuid save key       
classTag     : 'isjs-ac',   //When the class of active burying point is set to '', it is full collection, and the data will be large      
openInput    : 'true',      //Enable input acquisition or not     
openCodeErr  : 'true',      //Enable code exception collection   
openClick    : 'true',      //Enable click data collection      
openAjaxData : 'true',      //Whether to collect params of exception request (pay attention to the protection of privacy data)     
openPerformance : 'true',   //Whether to start page performance collection    
acblength    : 2,           //Click the element to collect the layers. The deeper the layers, the larger the data      

With the background interface, nodejs can be used to write a receiver to write logs       
Warning: it is better not to block this interface to avoid affecting page response     

The selector option is used to control the collection range of input, focus and blur events.   
It's actually a document.queryselectorall selector,     
Value reference：https://www.runoob.com/cssref/css-selectors.html    
The function of active burying point can be realized by specifying ID    

This condition is used to control the collection range of the input box, which is consistent with the function of the selector option, but the priority is lower than the selector option     
Warning: try not to collect element content of type password to avoid information disclosure      

It is used to implement the active burying point. It will verify whether the element class contains the specified tag    
Only the elements that need to be collected:<input class="qyd_aci_0001" />Set classTag to qyd_aci     

The key saved by the user UUID in the browser can be modified manually in case of conflict

It is not recommended to set the cookie storage period for too long to avoid affecting the storage of other cookies     

This option is used to limit the number of bubble layers for click events     
We use document. Addeventlistener ("click", function (E) {...}); to listen for click events     
Select the principle of event bubbling to collect, because some HTML content is generated dynamically by JS, and fixed selectors will be missed    
At present, click acquisition is an automatic burying point. All elements will be bubbled up and collected in two layers. The collected results will have many small elements, more specific display of user behavior      
Of course, click event also supports active embedding. You only need to untie 329 lines of commented code     
Warning: only one kind of active burying point and automatic burying point can be reserved    

1. User behavior data

    {
    	"uuid":"F6A6C801B7197603",                        //User uuid, valid for 5 days
