我选择了文本,我想在整个文本中获取此文本的start_index(this case = 0)和last_index(此案例= 39),而不包含类pivot
答案 0 :(得分:-1)
像这样的东西应该给你一个去:
function getSelectionText() {
var text = "";
if (window.getSelection) {
text = window.getSelection().toString();
} else if (document.selection && document.selection.type != "Control") {
text = document.selection.createRange().text;
}
return text;
}
$('#your_button').click(function() {
var whole_text = $('#content').text();
var selected_text = getSelectionText();
var index_of = whole_text.indexOf(selected_text);
var end_of = index_of + selected_text.length;
});
我从这里接受了这个功能:Get the Highlighted/Selected text
这是一个有效的工作: http://jsfiddle.net/a7bxp/
