jquery Method Binding (event registration) Code Summary

1. The most direct mode, directly passing a function object into the method function, such as the following click (), the advantages of the disadvantage of a glance to know

$ ("#btnComfirmChooseCompany"). Click (function () {    varCompanyName = ""; varCompanyID = ""; varhaschecked =false; varAllcheckbox = $ ("input[name= ' CompanyID ')");  for(vari = 0; i < allcheckbox.length; i++) {        if(allcheckbox[i].checked = =true) {haschecked=true; CompanyID= $ (Allcheckbox[i]). attr ("value")); CompanyName= $("#"+CompanyID). Parent (). Next (). text (); }    }    //slightly});

2. Equivalent notation, define function independently to a variable

function Comfirmchoosecompany (e) {  //e is optional parameter    // ibid., slightly }// or var function (){}

The variable is then passed into the JS event function, and the effect feels the same, but as to what the difference remains to be understood

$ ("#btnComfirmChooseCompany"). Click (    comfirmchoosecompany// can run, think ... What is the effect of adding parentheses to company? A: Comfirmchoosecompany run directly ); $ ("#btnComfirmChooseCompany"). Click (function() {         // equivalence notation, consider whether this business parenthesis can be omitted     });

3.bind method

$ ("#allCheck"). Bind function () {    $ ("[name = $chkItem]:checkbox"). attr ("Checked", $ (this). attr ("checked"));});

4.delegate method

$ ("Body"). Delegate function () {    $ (this). addclass (' Tr_color '). Siblings ("tr"). Removeclass ("Tr_color");});
