dhtmlxGrid实现setColumnHidden

Java代码


/** 设置TD隐藏或显示 by 20140814 **/

function cellHidden(cell, state) {

if ((state) && (cell.style.display != "none")) {

cell.style.display = "none";

};

if ((!state) && (cell.style.display == "none")) {

cell.style.display = "";

};

}

Js代码


this.rowsBuffer = dhtmlxArray();

this.rowsCol = dhtmlxArray();

/** 列是否隐藏-数组 by 20140814 **/

this.colHiddenArr = {};

Js代码

continue

Js代码

}

},

Java代码


_fillRow : function(r, text) {

if (aeditor)

aeditor.setValue(val)

} else {

r.childNodes[i].innerHTML = " ";

};

return r

},

调用API

setColumnHidden(ind, state)

ind - column index

state - true/false - hide/show column
