This example describes the solution that the checkbox in jquery repeatedly calls attr (' checked ', true/false) only for the first time. Share to everyone for your reference, specific as follows:

First look at the following code:

/**
 * All select
 /function Checkall () {
   $ ("input[name=ids]"). attr ("Checked", true);
 }
 /**
 * Do not select
 /
 function Uncheckall () {
   $ ("input[name=ids]"). attr ("checked", false);
 }

Problem Description:

The initial state checkbox is not fully selected, click the Select button to call the Checkall method, the implementation of the full selection, and then click the Full selection button to achieve a full choice, and then click the Full Selection button again, the result is a full selection of wood, and then repeatedly click on the wood has any reaction.

Instead of the attr method using the Prop method,

/**
 * All select
/function Checkall () {
  $ ("input[name=ids]"). Prop ("checked", true);
}

Solve the problem!
