JQuery Easyui Tree's oncheck event implementation code_jquery

Using firebug to check the generated HTML, I found that the checkobx is fake, just a span, changing the style back and forth, sweat

Copy code The code is as follows:

$(" .tree-checkbox", tree).unbind(".tree").bind("click.tree", function() {
if ($(this).hasClass("tree-checkbox0")) {
$(this).removeClass("tree-checkbox0").addClass("tree-checkbox1");
} else {
if ($(this).hasClass("tree-checkbox1")) {
$(this).removeClass("tree-checkbox1").addClass("tree-checkbox0");
} else {
if ($(this).hasClass("tree-checkbox2" )) {
$(this).removeClass("tree-checkbox2").addClass("tree-checkbox1");
}
}
}
_2eb($(this) .parent());
_2ec($(this).parent());
return false;
});

Then look at its onClick event script
Code

Copy code The code is as follows:

$(".tree-node", tree)
....
bind("click.tree", function() {
$(".tree-node-selected", tree).removeClass("tree-node-selected" );
$(this).addClass("tree-node-selected");
if (opts.onClick) {
var _2ea = this;
var data = $.data(this , "tree-node");
opts.onClick.call(this, { id: data.id, text: data.text, attributes: data.attributes, target: _2ea });
}
})

Modify its check script accordingly

Copy the code The code is as follows:

$(".tree-checkbox", tree).unbind(".tree").bind("click.tree", function() {
if ($(this).hasClass( "tree-checkbox0")) {
$(this).removeClass("tree-checkbox0").addClass("tree-checkbox1");
} else {
if ($(this). hasClass("tree-checkbox1")) {
$(this).removeClass("tree-checkbox1").addClass("tree-checkbox0");
} else {
if ($(this ).hasClass("tree-checkbox2")) {
$(this).removeClass("tree-checkbox2").addClass("tree-checkbox1");
}
}
}
_2eb($(this).parent());
_2ec($(this).parent());
return false;
}).bind("click.tree", function() {//gzl increase
if ($(this).hasClass("tree-checkbox1") && opts.onCheck) {
var _2e9 = this;
var data = $.data( this, "tree-node");
opts.onCheck.call(this, { id: data.id, text: data.text, attributes: data.attributes, target: _2e9 });
}
});

But I couldn’t get the Data value, and finally I had to $(this).parent().click(), click event plus check to determine whether it becomes selected, two The event uses one method, ugh
I really hope that a new version will be released, or that some expert will change it, my ability is too limited.
