jQuery implements the practice of changing the position and size of div by dragging the mouse
|
To achieve an effect similar to Windows forms, drag in the middle to change the position of the div, drag on the edge to change the size of the div, and the mouse changes to the corresponding shape at the corresponding position as shown in the figure: (The screenshot does not show the mouse)
The code is as follows:
$(".test1").mousemove(function(e){
$(".test1").unbind("mousedown");
$(".test1").css("cursor","default");
//$("span > b").text(parseInt($("div").width()));
var left = $(".test1").offset().left;
var top = $(".test1").offset().top;
// If the mouse is in the middle if(e.clientX - left > 10 && e.clientX-left < parseInt($(".test1").width()) - 10
&& e.clientY - top > 10 && e.clientY-top < parseInt($(".test1").height()) - 10) {
$(".test1").css("cursor","move");
$(".test1").mousedown(function(e) {
var ismove = true;
var x = e.pageX - $(".test1").offset().left;
var y = e.pageY - $(".test1").offset().top;
$(document).mousemove(function(e) {
if(ismove) {
$(".test1").css({"left":e.pageX - x, "top":e.pageY - y});
}
}).mouseup(function() {
ismove = false;
});
});
}
//If the mouse is in the upper left corner if(e.clientX - left < 10 && e.clientY - top < 10) {
$(".test1").css("cursor","nw-resize");
$(".test1").mousedown(function(e) {
var ismove = true;
var y = e.pageY - $(".test1").offset().top;
var h = e.pageY + parseInt($(".test1").css("height"));
$(document).mousemove(function(e) {
if(ismove) {
$(".test1").css({"height":h - e.pageY, "top":e.pageY - y});
}
}).mouseup(function() {
ismove = false;
});
});
$(".test1").mousedown(function(e) {
var ismove = true;
var x = e.pageX - $(".test1").offset().left;
var w = e.pageX + parseInt($(".test1").css("width"));
$(document).mousemove(function(e) {
if(ismove) {
$(".test1").css({"width":w - e.pageX, "left":e.pageX - x});
}
}).mouseup(function() {
ismove = false;
});
});
}
//If the mouse is on top if(e.clientY - top < 10 && e.clientX - left > 10 && e.clientX-left < parseInt($(".test1").width()) - 10) {
$(".test1").css("cursor","n-resize");
$(".test1").mousedown(function(e) {
var ismove = true;
var y = e.pageY - $(".test1").offset().top;
var h = e.pageY + parseInt($(".test1").css("height"));
$(document).mousemove(function(e) {

//If the mouse is in the upper right corner if(e.clientY - top < 10 && e.clientX-left > parseInt($(".test1").width()) - 10) {
$(".test1").css("cursor","ne-resize");
$(".test1").mousedown(function(e) {
var ismove = true;
var y = e.pageY - $(".test1").offset().top;
var h = e.pageY + parseInt($(".test1").css("height"));
$(document).mousemove(function(e) {
