Code for selecting textarea text under javascript compatible with firefox_form effects

May 16, 2016 pm 07:03 PM
firefox javascript

主要用到的js代码

复制代码 代码如下:

function getSelectedText(){
        var selectedText;
        var textField=document.getElementById('inputTextarea');
        if(window.getSelection) selectedText=getTextFieldSelection(textField);//getTextFieldSelection(document.getElementById("inputTextArea"));
        else selectedText=document.selection.createRange().text;
            alert(selectedText);
    }

    function getTextFieldSelection(e){
        //var oEvent=arguments.callee.caller.arguments[0];
        if(e.selectionStart != undefined && e.selectionEnd != undefined)
            return e.value.substring(e.selectionStart,e.selectionEnd);
        else return "";
    }

千万别相信我说的事情,我从来就没有这么勇敢过,这么壮烈过。我不断发誓要老老实实讲故事,可是说实话的愿望有多强烈,受到的各种干扰就有多大。我悲哀地发现根本就无法还原真相。记忆总是被我的情感改头换面,并随之捉弄我,背叛我。把我搞得头昏脑胀,真假难辩。
